Pond Filtration: What type of Filter System do you need. (2022)

Pond Filtration: What type of Filter System do you need. (1)

There are two main types of filter that you would use in your garden pond to keep the water clear and the fish healthy, but you will need a filtration system for those filters to work.

Novice pond keepers and beginners think the filter system keeps the pond sparking clean and healthy by just removing physical dirt from the water but this is not the case.

Yes there are filters within the system that do remove waste from your pond but it’s not the full story, there are harmful toxins in the water that also need to be filtered out, read on to find out what the filters do, why you need them and how they are used in a filtration system.

Do you need to have a filter system in your pond?

No not all ponds need to have a filtration system, it all depends on the type of pond you have.

If you don’t intend to have fish in your pond there’s no reason to have a filter.

If you are building a wildlife pond with lots of plants you can choose not to use a filter, you could even get away with having a wildlife pond with a few fish, as long as there is plenty of plant life withing the pond to create a well-balanced ecosystem.

If you do decide to build a wildlife pond, it may take some time to get a good balanced nitrogen cycle working without a filter system in place, but it can be done, just give it time.

If you want to keep a good stock of fish in your pond you must realise they produce waste, both in liquid and solid form which goes straight into your pond water, so you will need to have some sort of filtration system to clean it up, as well as other debris that falls into your pond along the way.

What you need to understand, is a fishpond is a closed environment and all the water is trapped within the pond, not like natural ponds that have streams with fresh water passing through, add fish to the equation and that static pond water will soon become dirty and full of toxins.

The actual filter system that you will need depends mainly on the size of the pond, how may fish you intend to stock and where you plan to keep the system.

This can range from a small filter system for a small pond with goldfish right up to a large multi-chamber drum filter system for a large pond full of Koi, but the principles are the same.

What types of filters are there?

There are two main filters that are used in your filtration system each one having it’s own job to do to keep your pond well-balanced, clean and healthy for your fish.

Mechanical pond filters.

The mechanical filter is the first filter your water hits in a filtration system, these take out the large particles of dirt suspended in the water.

This first stage of filtration is very important to your system, it’s there to stop any large particles of waste getting to the next stage which is biological (I will get to that in a bit).

If large particles did get past this filter it could clog the biological filter, so it’s best to get this stage right or you will have problems down the line.

There are a few methods that can be used for mechanical filtration but the most commonly used is sponges of various grades which traps the large particles of waste.

For your larger ponds you may want to go for more mechanical filtration using a multi-chamber system that has different mechanical media in each container.

Mechanical filters need to be cleaned on a regular basis to ensure they don’t get blocked and reduce the flow of water in the system.

Biological pond filters.

Once the pond water has passed through the mechanical filters in enters stage two of the filtration system, the biological filter.

The biological filters job is to remove harmful toxins that are present in the water such as ammonia and nitrate.

Having a nice clear pond doesn’t mean the water quality is good, there could be toxins in your pond such as ammonia, nitrites and nitrates which cannot be seen, this is where the biological filters play their part.

These filters are designed to host large colonies of beneficial bacteria that convert the harmful and sometimes dangerous toxins into safe water for your fish.

Typical biological filter media can be anything from foam to plastic bio balls and bio glass to lava rock, but what they all should have is a large surface area for the good bacteria to grow on, the more bacteria the filter holds the more efficient the filter becomes.

For biological filters to work at their best they need a good mechanical filter to remove the solids before getting to them, a large colony of bacteria living on the bio media and a continuous supply of oxygen through a good flow of water to keep the bacteria alive.

It takes 4-6 weeks for a colony of bacteria to build up to a point where it reaches a good working level, so if it’s a new pond you don’t want to introduce fish until the levels are met.

Biological filters do not need to be cleaned unless there is a major problem, if you clean them you will wash away all that good bacteria that has taken so long to colonise and you will be back to square one.

Ultraviolet clarifiers.

Now I know these are not really filters in the way that mechanical and biological filters work, but they do play a part within the filtration system.

An ultraviolet clarifier (UVC) is designed to remove single cell algae, that’s the algae that cause your pond to go green.

The pond water is pumped into the clarifier and the ultraviolet lamp kills the single cell algae, once dead the algae clumps together and is collected and broken down by the biological filter or captured by the mechanical filter.

These UVC’s can be integrated within the pond filter or used as an inline standalone unit.

UV lamps have a short life and should be replaced at least once a year, if you are replacing your lamp the best time to do it would be the spring as your pond wakes up, that way you will have good UV protection through the summer months when algae is at its strongest.

Pond filtration systems.

Well now you know what each filter does it’s time to look at filtration systems.

Pre-filter.

A pre-filter is a simple mechanical filter that blocks large debris and solids before they are sucked into the pump.

Using a pre-filter is not necessary, but it can help to extend the life of the pump and improve its efficiency, just make sure you clean it on a regular basis to keep the water flowing.

Pond skimmer.

A pond skimmer is installed at the edge of your pond and will house your pond pump.

With the pump running the water is drawn to the skimmer bringing with it debris floating on the surface of the water.

The water with the debris falls through the mouth of the skimmer onto a coarse mechanical filter or a basket that captures all large debris that can be removed with ease, this system can be classed as a pre-filter because it catches the big debris before it reaches the pump.

(Video) How to set up a Pond Filter and Pump - Pond Filtration

If you are going to fit a skimmer it needs to be positioned at the opposite end to your waterfall or were the water is returned to the pond, this is to make sure you have full circulation of the pond water.

You can also use a floating surface skimmer that has its own built in pump, these are just placed into your pond and plugged in to your electricity supply, the skimmer will draw the floating debris into it’s basket, to clean just take out the basket, clean it out and replace.

These are great devices if you have a lot of falling leaves from nearby trees and plants or grass cuttings getting into your pond.

Another good benifit of having a skimmer is the pump is easy to remove for maintenance.

All in one pond pump/filter.

As a novice pond builder it’s easy to see why these look like the best and easiest filtration system to use.

After all they have a pump, filters and a UVC all combined in one small compact unit that you just pop in your pond and be done with.

Unfortunately all is not what it seems, yes they do what they say they will do, but they are only useful for a smaller pond or a pond that has very few fish.

If you have a small pond with a few fish then your in luck but anything bigger and it will struggle, that’s not to say you can’t use it alongside a larger filter set up.

Let’s say you have a full system with pump and filters but you fancy a waterfall using a separate system, you can buy a small waterfall pump that would just run the waterfall or you could use an all in one which gives you the added benefits of filters and a UVC.

Flow through filters.

These flow through filters also known as box filters are perfect for the medium to large pond.

They are a simple design that contain the mechanical and biological filters inside the box, some even come with a UVC.

They are designed to sit outside the pond, but must be positioned above the water surface, the water is pumped through the box passing through the filters before flowing back into the pond through gravity.

The outlet pipe can be directed back into the pond or into a stream or waterfall, as long as the box is higher than the water feature it’s returning the water too it will work.

One of the problems of running this system is trying to hide the box, but it is a tried and tested method and is good value for money.

Waterfall filters.

These waterfall filters act in a very similar way to the flow through filters, water is pumped into the waterfall filter through mechanical and biological filters and back out through gravity.

The difference is the waterfall filter has a ledge that the water spills over to form a waterfall rather than having outlet pipes that you would direct into a purpose built waterfall.

They can be set at the edge of your pond so the water spills over the ledge straight into your pond giving a pleasing waterfall, still hard to hide though.

Pressure filters.

Pond Filtration: What type of Filter System do you need. (2)

A pressure filter comes in a big round container that can be placed anywhere around or near to the pond.

(Video) How a pond filter works and why you should build your own

Inside the pressure filter you would usually find mechanical and biological filters along with a UVC, but not all, you can get some with just mechanical filtration and some might not have the UVC.

They work by maintaining a constant water pressure (hence the name) and flow, being pressurised they are perfect for using with waterfalls or other water features as they can push water uphill to the top of any water feature.

They have an inlet and outlet for water flow plus another outlet for cleaning, the submersible pump in the pond pumps the water in through the inlet pipe which then passes through all the filtration and exits the outlet pipe.

The outlet pipe can be directed up to a waterfall or to another water feature or straight back into the pond.

Most have a cleaning system combined within the unit, this is when the cleaning outlet is used, a twist of a knob, a turn of a handle, or a pull/push on a handle depending on the make of pressure filter will clean the filters and the dirty water will be discharged through the cleaning outlet without getting your hands wet, they usually come with an indicator on top of the unit to tell you when it needs cleaning.

They don’t have to be above the waters surface like the flow through filters, so they can be placed anywhere, in fact you can bury them in the ground just leaving the top sticking out which is what most people do.

The great thing about burying a pressure filter is how easy they can be disguised so you wouldn’t even know they were there.

Multi-chambered filter system.

Multi-chambered filters are just a series of flow through filters that are linked together through pipework.

The first chamber will have mechanical filtration, the pumped water passes through the foam taking out the large waste before moving on to the second chamber.

The second chamber is for biological filtration and you could pump into a third chamber also containing bio media.

They don’t come with a UVC but these can be added for full protection.

Shower filter.

These shower filters are not as common as the above filters, but they do a great job at filtering your pond water.

They are simply trays that sit on top of each other and each tray is filled with a filter media.

On top of the trays is a spray bar that takes the water from the pond pump and sprays it onto the top tray, it passes through the top tray into the next tray using gravity.

Once it has passed through all the trays it is dispatched straight into the pond giving a pleasing waterfall effect.

You can decide on how many trays you want and what media is used in each tray, for instance you could have a three tray system, the top tray filled with foam for mechanical filtration and the bottom two filled with pumice for biological filtration.

If you wanted too you can use all the trays for biological filtration as long as you used some sort of mechanical filtration first.

(Video) Which Pond Filter Is Best? Canister, Box or All in One?

Cleaning would be done by turning of the pump and cleaning the mechanical foam filters in a bucket of pond water, replace the cleaned foam and turn the pump back on, there’s no need to clean the biological media.

Drum filters.

Another filtration system that’s not commonly used but if your looking for the ultimate mechanical filtration system this is one to go for.

They can be pump fed or gravity fed but if you go for gravity fed you need to have a bottom drain in your pond.

They are designed to remove the biggest particles right down to the smallest particles of waste.

Inside the unit is a drum that has a very fine mesh that catches all the waste, once it senses the filter needs cleaning the drum turns, it then uses water from the pond to spray onto the drum to remove the waste, the waste is discharged through a separate outlet. This is all done automatically.

Once the pond water has passed through the drum filter it needs to go to a biological filter in this case a moving bed module.

The moving bed module is filled with Hel-X media which is a very efficient home to friendly bacteria.

The reason the Hel-X is moved around is to give it a a permanent supply of oxygen for the bacteria and it also acts as a self-cleaning function.

As the media moves about it knocks of any dead or old bacteria making way for new bacteria to grow.

There is one last module that can be added to the system which can house extra bio-media or if using the system as a gravity fed system houses the pump and UVC.

A UVC can be added to the inlet just before the drum to kill the one cell algae and the drum will remove the clumped up algae.

So which is the best filter system for you.

First things first, there is no such thing as over filtering a pond, go for the largest filter system that you can, you can never have too much filtration.

On the other hand your pond could get into real trouble by under filtration, even if the filter system says it will filter the size of your pond always go larger, going larger will future proof your pond as well as giving greater results.

Before buying a filter you really need to know what it’s needed for, it makes no sense to go for the ultimate filter system if you are just going to have a couple of goldfish in your pond, and the opposite of have a large selection of Koi with the minimum amount of filtration.

If you have a small pond with just a couple of goldfish then you could probably get away with the all-in-one pond/filter but keep an eye on the water and test regularly.

For a medium pond the flow through or pressure filters are going to be a good solution, just make sure they are more than adequate for the size of pond and the amount of fish you want to keep.

For a large pond with lots of fish you can get away with the very large flow through filters or even better the muti-chamber filters as well as the pressure filters, if you find one filter starts to struggle you could add extra filters to compensate without having to start again. You could have two pressure systems or a pressure system to feed the pond and a flow through system to feed a waterfall.

For the dedicated Koi pond with lots of large fish you will struggle unless you have a good filtration system, the drum system would be the way to go but it is expensive compared to other systems.

Whatever system you go for you need to test the water regularly to make sure its doing it’s job, just because the water is clear doesn’t mean the water isn’t full of harmful toxins.

An Ultra Violet Clarifier filter kills green water to keep the water clear, while a Biological Filter looks after the water quality to keep the fish healthy and happy.. Please Note: If you have a pond with extremely high fish stocks or just koi it is worth considering a larger filter as it is impossible to over filter a pond biologically.. An ultra violet clarifier is an electrical unit through which water is pumped before it enters the biological filter, and its purpose is to eliminate green water and reduce harmful bacteria in the pond.. Gravity return Biological filters (Box Filters) have a gravity outlet therefore the outlet must be higher than the point of return.Gravity outlet filters, keep the return pipe full bore, gently angled down and as short as possible.To maximise water flow ensure the largest possible inlet hose is used.Most top outlet filters will work better if partially buried keeping the sides tight around the media when full of water.Always follow manufacturers instructions for individual model requirements. Filters must run 24 hours a day (Certainly from March to October).Pass your pond water through the filter at least every 1-2 hours.Regularly check pump pre-filter to ensure good flow.Remember a filter will take weeks to become biologically active.Clear water does not mean healthy water.. Test your water regularly.Use a bacterial supplement to start and improve filter performance.Always clean filter material in a bucket of pond water not in tap water.Only clean media when flow is being inhibited.

A good pond filter is key to having a successful pond. Filtration keeps the pond water clear, oxygenated, and healthy for the fish living in…

One popular feature is UV light filtration.. Similar to aquarium filters , the primary function of a pond filter is to keep the water oxygenated, which helps create a suitable environment for beneficial bacteria.. Pond Filtration. When choosing the right filter size for your pond, choose a filtration system that has sufficient flow rate.. The rule of thumb is to install a filter with a gph rating of 1.5 times the number of gallons in your pond.. The flow rate of your filtration system will influence the oxygen level in your pond, which is very important.. Some of the most common types of filtration in a pond filter are, mechanical filtration, biological filtration, and UV filtration.. Removing the debris and sediments in the pond water is important because it keeps the water visibly cleaner, and it prevents the debris from clogging the biological filtration.. Biological filtration within a pond filter houses the beneficial bacteria, which processes the organic waste material.. Over a period of time, the beneficial bacteria will slowly establish itself on the biological filter media.. Therefore, if you are installing a new filtration system, it is best to allow the pond to cycle before adding lots of fish.. Biological filtration is one of the most important functions of a pond filter.. Therefore, this unit will support a pond of approximately 900 gallon in size.. Considering the fact that it features a UV light at this price point, the SUN Grech CPF-2500 is certainly the one of the best pond filter currently available.

Most beginners believe a pond filter works by removing physical dirt and it is this which keeps the water sparkling clean.. This is done by the helpful bacteria breaking down the initial toxin Ammonia into Nitrite.. A different type of helpful bacteria then breaks this dangerous Nitrite down to Nitrate which then can be absorbed by plants as they grow and is harmless to fish except in high concentrations.. Some advanced filter systems can strain out more solids from the water, but it has to be remembered that these still have to be biologically broken down unless physically removed by flushing or draining.. Low Fish Stock : For ponds which are mainly plants with a no or few fish and with normal sunlight levels.. High Fish Stock: For ponds with less plants and a higher stocking level of fish or exposed high sunlight levels.. Ultra violet clarifiers are available as a standalone unit to be added to existing biological filtration units or more commonly they are combined with a biological filter.. An ultra violet clarifier is an electrical unit through which water is pumped before it enters the biological filter, and its purpose is to eliminate green water and reduce harmful bacteria in the pond.. As the water is passed through the unit, it is subjected to high levels of U.V.. They are complex units to install and expert advice is available in our stores.. It is usually obvious when they need cleaning by either water flow reduction through a pressurised filter or by some water passing over media in gravity filters.. Do not clean all the media at once, but stagger cleaning to keep a high population of the helpful bacteria.. Filters must run 24 hours a day (Certainly from March to October).Pass your pond water through the filter at least every 1-2 hours.Regularly check pump pre-filter to ensure good flow.Remember a filter will take weeks to become biologically active.Clear water does not mean healthy water.. Test your water regularly.Use a bacterial supplement to start and improve filter performance.Always clean filter material in a bucket of pond water not in tap water.Only clean media when flow is being inhibited.

Different ponds need different hardware, & knowing what pond filter you need can be tricky. We aim to give clarity & options to pond keepers.

It needs a pond pump to supply it with water, the pond filter then acts as a sewage treatment plant, removing waste from the water and also in the case of a UV clearing the water as well. You can have a filter without a UV but don’t expect to have clear water.. There are many different types of pond filter, and once you have established what size you need it’s all down to where you want to put it and how much maintenance you want to do.. These are becoming very popular as you have one piece of equipment sitting in the pond which pumps water, filters the water and has a UV to kill Algae.. Manufacturers such as Oase, Hozelock, laguna and Bermuda all have at least one range of pressure filters.. These make sure you get the right sized pond pump with your pond filter.. Water can then pass from your pressurized filter up to a water fall or feature.. The down side to these filters is they often have a limited amount of media in them due to their smaller size and unless you choose one with a cleaning mechanism you have to open them up each time you want to maintain the filter.. The outlet of these filters MUST be above the water level in your pond for the water to fall out of the filter and back to your pond.. Pump and filter packages are also available and some of the manufacturers have made these filters even easier to clean as is the case of the OASE Biosmart systems

Filtration is an important part of keeping a pond clean and clear. There are a few different types of filtration that can be used for a pond, and the type

A pond may require a sand or gravel filter, a mechanical filter (such as a pump and strainer), or a chemical filtration system.. A pond filter system should be installed if the water quality in the pond is questionable.. Some of the types of water filters that can be used in a pond include sand and gravel filters, activated carbon filters, and ultraviolet sterilization filters.. Another way to filter your pond water is to use a pump.. Yes, koi can live in a pond without a pump, provided that the pond has good water quality and the fish are given adequate food and water.. A Brita filter can technically filter pond water, but it is not recommended because the filter will not be able to remove all of the contaminants.

Three types of pond filters are available in the market, which are biological, mechanical, and sterilizers.

In addition to plants, fish, aeration, and rocks and gravel, a low-maintenance ecosystem pond requires adequate filtration to keep the water clean and clear.. A good biological filtration system, teamed with a proper mechanical filter to remove solids before the water enters the biological filtration unit, is the most effective way to filter water.. As water enters the skimmer, the large debris is caught in the skimmer basket and the water is then further filtered through the horizontal mat.. Biological Pond Filtration Goes to Work The biological filter receives water that has already passed through the mechanical filter, or skimmer, typically placed on the opposite side of the pond.. The water then flows from the bottom to the top of the filter, traveling through filter media housed inside the unit.. If the pump isn’t running, the waterfalls aren’t flowing, and aeration is eliminated from the necessary equation to maintain an ecosystem pond.. Nitrates are also absorbed by aquatic plants and algae during their growth processes.. Surface area is provided by filter media, rocks, and gravel.. The Role of Aquatic Plants Another important component to pond filtration is the use of plants.. Algae control is not the only way plants help create a low-maintenance ecosystem pond.. Low-Maintenance Pond Experience To keep pond water quality high, the simple process of repeatedly turning the water over through the mechanical and biological filters is needed in order to create a naturally balanced, low-maintenance ecosystem pond.

Many pond owners experience water quality issues that often result in suffocated fish among other issues.. Some of what you’ll find include types of pond filtration, filter types, and figuring out your pond’s volume.. When combining these benefits, beneficial bacteria create a habitable environment for aquatic organisms.. These are natural filters where water flows through the bottom of your filter and afterward moves upward.. As water passes through your filter chambers, the light will kill organisms like parasites, bacteria, fungus, and algae.. The ultraviolet lights can damage medications that your fish might be taking.. As the water fills in this filter, it will first move through a first filter that will catch the bulk of your pond’s debris.. The volume that you will need to calculate depends on different types of ponds.. To prevent your filter from overworking itself when the environment changes , you will need to adjust your pond’s volume number to figure out your effective volume:. From there, if your pond has more than 101 fish per 1,000 gallons, you will need to multiply your effective volume by 1.25 to find the total required filtration.. Once you determine your volume and filtration, find filters that companies rate to run 1.5 times your required filtration.. To find the right filter, you will need to consider your goals and afterward choose what type of filter you’ll need.

Pond filtration is necessary for maintaining a clean and balanced ecosystem in your pond. There are different kinds of filters and filtration, and each has its advantages for certain types of ponds. This process can be overwhelming, so to help you out we’ve put together some essential information about pond filtration systems and guidelines on choosing the right one for your pond. To better appreciate why filtration is a good idea, you need to understand how it works. Filtration is needed to eliminate muck, particles, and biological wastes from the water that are unhealthy for the pond. A properly installed filtration system will pull water from the bottom of your pond and circulate it, along with essential nutrients and oxygen, throughout the water garden. There are natural ways of filtering, but help from man-made filters and pumps help speed up the process of filtration. Even if your pond is solely decorative, a filtration system will help prevent stagnation, reduce algae growth, impede insect pests, and clean the water to be used in a beautiful water display. Now that we understand why filtration is important, let’s talk about the different types of filtration methods. The right choice for your pond will be based on the size of your pond, water depth and volume, and the number of plants and fish that are present in it. Types of Filtration Mechanical or physical filtration refers to the removal of particles of debris by means of passing the pond water through various filtration media. Skimmers, canister filters, and pre-filters are common examples of filters that mainly rely on mechanical filtration. Depending on the type of filter, this filtration method keeps the water clear by straining, skimming, or trapping leaves, muck, algae, and any other form of debris. This helps to prevent clogs in other pond equipment as well as reduce the build-up of debris from settling on the bottom. When run through a mechanical filter, water will not be treated and will retain any toxins or harmful substances it contained prior to entering the filter. This type of filter is not recommended as the only source of filtration for a pond containing fish or aquatic wildlife. Mechanical filtration systems need to be regularly cleaned, at least once a week, to ensure that the filter is functioning well and is free from excess solid waste. Chemical filtration is more commonly used in aquariums, but some pond filter systems do use it. As the name implies, it uses chemicals to remove organic and inorganic pollutants with specialized media like carbon and resins, usually in a loose, bagged, or pad form. This method is usually used to manage ammonia levels or to remove any traces of medication or treatment used in the pond. Biological filtration removes toxins from your pond water and provides a safe and healthy environment for your aquatic wildlife. Biological filtration works by incorporating a filter in or around your pond that uses bacteria in order to break down toxins coming from fish, excess food, and decaying organic material. These types of filters break down the ammonia in the water into nitrite. Later on beneficial bacteria will develop, transforming the nitrite to nitrate, which are not as harmful to fish and are used by plants. Biological filters typically clean the water through mechanical filtration as well as treating the water and removing toxins. Many pond owners use only biological filters due to the dual filtration associated with this method. Ultraviolet Clarifiers are not really considered filters, but UV clarifiers are often used in combination with a filter or actually inside the filter itself. UV clarifiers are designed explicitly to tackle the problem of green murky water due to algae blooms. UV clarifiers kill floating algae, bacteria, and other microorganisms that flow through the clarifier and return clear, safe water back to your pond. Filtration systems include a filter and a pump. As mentioned above, filters are used to remove any unwanted solid particle that can damage your pond. Pumps, on the other hand, are vital for passing water through the filter. As a pond owner, you must first decide whether your pond will require complete biological filtration due to aquatic life or, in the case of a small decorative pond, simply require a mechanical filter. Filters There are many different types of filters. There are combination, external, and submerged filters. Combination filters are multi-functional and perform the duties of different types of filtration. For instance, a multi-filter may include sponge media that absorbs debris and an empty chamber to add

Now that we understand why filtration is important, let’s talk about the different types of filtration methods.. The right choice for your pond will be based on the size of your pond, water depth and volume, and the number of plants and fish that are present in it.. These types of filters break down the ammonia in the water into nitrite.. Biological filters typically clean the water through mechanical filtration as well as treating the water and removing toxins.. Many pond owners use only biological filters due to the dual filtration associated with this method.. Filtration systems include a filter and a pump.. When deciding between these two filter types, consider important factors such as pond size, plumbing, required electricity, and installation.. Water pumps are perhaps the most important piece of equipment for a good filtration system.. You should also become familiar with pump pressure and pump volume.. The filtration system is almost certainly the most important piece of mechanical equipment in your pond, so spending more on a system that is easy to maintain and of the best quality is to your advantage.

By the term “biological” what we mean is that beneficial bacteria (a natural occurring critter) is provided a home in the filter and these good micro bugs help clean up any organic things in the water which includes both the solid material, and the unseen substances as well.. This helps create a safer environment for fish and can even help limited unwanted plant growth such as algae.. You may find some pond filter models that include a uv light along with a biological filter system.

Article from Koicare.com Koi ponds and koi keeping are gaining popularity in the U.S. and in many parts of the world. Koi ponds are as varied as the places they are found. Ponds can be deep or shallow, be natural or constructed with liners or concrete but no matter what form they take the filtratio

Biological filtration cultures aerobic (nitrifying) bacteria that will help break down the chemical components of fish waste.. The water flowing into the bottom drain will move into a settlement tank, which is then allowed to settle to the bottom of the tank while the surface water is sent towards the pump.. This filter helps remove more waste from the old water, ensuring cleaner water is then pumped back into the pond.. Skimmers are your other mechanical filtration system.. Floating debris will effectively be removed via the skimmer, but without it all things would ultimately make it to the bottom drain.. As a result, a pond owner needs both physical and chemical means of removing these wastes from the pond.. Additionally, those solid wastes come in different sizes and need to be filtered out accordingly therefore a good mechanical filter will have multiple stages.. until making its way to biological filtration.. To ensure this happens you need a pond with a large surface area and plenty of supplemental oxygenation via waterfalls, fountains, aquatic plants or diffusers .. The all-in-one systems like the Life gard Aquatics are often submersible units that have the mechanical filtration, biological filtration, UV clarifier and pump all in one compartment..

Do you need a pond filter, and if so, which one? We show you your options in this easy to follow guide.

Pond water often goes green, and the combination of a pond pump , pond filter and an ultraviolet clarifier can prevent the common problem of green water.. Pond fish also produce waste but are not equipped to live in their own waste, so fish pond filters can convert fish waste and prevent it from getting polluted.. There are two small negatives with box fish pond filters - firstly they are large, so may be unsightly if situated at the poolside and not hidden, and secondly, as they work via gravity, they need to be situated at the highest place in the system for water to return via gravity to the pond.. Just like box filters they contain biological and mechanical filter media, water is pumped to them by a pump in the pond, and models with built in UV are available to prevent green water.. Koi ponds are typically designed with large fish and large amounts of waste in mind, and are deep, with nothing to cause or collect waste in the pond like pond plants.. And unlike standard box and pressure filters, koi ponds are often run as gravity fed systems , with a bottom drain and surface skimmer built into the base and side of the pond, then a large filter is placed next to the pond, and pump and uvc are outside of the pond too.. Once in the filter waste is physically removed first, then treated biologically by lots of biological filter media, before a powerful external pump sucks water from the filter, pumps it through a UVC, then returns it to a pond.. All-in-one pond filters are only designed for small pond filtration however, and if used as the sole form of filtration in large fish ponds, they may fail to break down all the waste and keep the water clear, or they may clog up.. For koi carp, pond keepers often double the filter capacity again, so aim for a filter capable of filtering 6000 litres volume, for the above pond with koi.. There is no limit to the size of pond filter you put on your pond, and the larger the filter and UVC, the better your water quality will be.

There are many choices when it comes to filters. Here is a road map to help you decide what kind of system to consider, depending on what you are building, your customer’s circumstances, and preferences. Is one type enough or do you need more than one filter style to do the job?

And if your project is to build a koi pond then you better make sure to include plenty of biological and mechanical filtration.. These canister filters often have foam media functioning as both mechanical and biological filtration, but cleaning of debris may interfere with biological filtration.. These filters are usually small and require fairly frequent cleaning, but are a suitable add-on to small existing ponds or for very small ponds.. Models include Aqua Ultraviolet’s Ultima II and AquaDyne.. These pressurized filters are often used in koi ponds or heavily stocked water gardens.. Common media used in waterfall filters include plastic ribbon, bio-balls or filter mats.. Often made from a 55-gallon plastic drum or similar container, water is typically pumped into the bottom, then it up-flows though various possible filter materials allowing a mixture of mechanical and biological filtration.. The water should flow somewhat slowly though a heavily planted bog.. A bog filter is a great add-on to a koi pond.

Especially as the stocking levels of fish are much higher in a garden pond than in the wild, all ponds need a filtration system to keep the water clean, clear and healthy.

The numbers on filters normally indicate the maximum pond size they are able to filter, however you must be careful with this because these numbers usually mean WITHOUT fish.. You will also find that pond filters will list a maximum flow rate, this is the maximum rate of water per hour the filter can handle.. Too large a pump can overflow a box filter or blow the seals on a pressure filter, too small a pump will mean the filter is unable to efficiently filter the pond.. These filters are great if you want to hide the filter but require something a little more substantial than an underwater filter.. The issue with pressure filters is that they do need more maintenance than a box filter but not as much as an underwater filter .. These filters are probably seen as old fashioned but you can’t beat them when it comes to the sheer volume of water they’re able to filter and they’re not normally as expensive as the equivalent pressure filter.. The easy clean systems built into pond filters will normally use the water from the pond to clean the foams and then the dirty water, which contains useful nutrients, is sent into a flower bed.

I’m happy to take this opportunity to expand on what I wrote four years ago about undergravel filtration.

They were familiar with undergravel aquarium filters and felt that undergravel pond filters would behave in the same way.. Could this happen in a pond undergravel filter?. Of course, this is true with any pond using any type of filter system.. An advantage to having an undergravel filter is that debris is generally not an issue, unless it’s so large that it actually prevents the pump from being able to pull water through it.. Water will continue to flow through all areas of the filter, and the filter will continue to work as advertised.. The next logical question is, “Why doesn’t it build up enough debris to clog it up?” Simply put, in a properly constructed system, there should be sufficient space between the gravel so that debris continues to move and break down, eventually exiting though the filter.. It is a good idea to have another type of filtration system, such as a skimmer, that is designed to remove floating debris from the pond.. I would recommend a secondary filtration system for any outdoor pond, regardless of its primary filter system.. To meet these requirements, I designed the system with a submersible pump in a sealed box with an open pipe leading into it from half of the undergravel filter.. The output from this pump went to the other half of the undergravel filter as a pressurized filter.. Because the filter is in the pond, it can run without having to lift water above the surface of the pond.. If designed correctly, the filter should draw water from the entire bottom of the pond and bring it to the surface, where it can absorb oxygen from the air.. An airlift system was integrated by Magnolia Ponds (photo courtesy of Max Taylor).There are always going to be some who believe that undergravel systems promote the production of hydrogen sulfide.

2) More importantly much of the solids that fail to be removed by the mechanical stages of your filter will be deposited in the biological part of your filter where they can clog the media, render the biological stages ineffective and cause the nitrifying bacteria to die - result - not only is your mechanical filter not working properly but this will therefore prevent your biological filtration working as well - not good.. Other mechanical filtration devices such as the pre-filter sieve, bead filters, filter brushes, foams and wadding all work by straining or sieving particles from the water and whilst they can all work effectively, they all require maintenance and/or will not filter out very fine solids.. This is because with pump fed filters, the in pond pump is picking up solids from the pond and turning this into an 'organic soup' before depositing this into your filter, thus giving the mechanical part of your filter a much more difficult job to do in terms of removing solids from the water.. Biological filtration is actually a much simpler proposition than mechanical filtration, and if we assume that the mechanical part of your filter is working effectively, clean water, devoid of most of the solids will be passing into the biological stages.. In order to ensure the biomass has an adequate supply of oxygen, air should always be pumped into the filter, by placing air stones under the media , on the filter grids and air introduced by way of an air pump.. last updated 10th April 2017 At Koi Water Garden, we are able to offer competitive prices on not only high quality koi, but also on koi related goods such as complete filter systems, Vortexes and filter media.

If you are using a growbed system with a density lower than 1, you don’t need additional solids filtration.. Get Started with Aquaponics. The motion of the water will create a swirl or vortex, and given enough time (retention time), the solids will settle at the bottom, and the clean water will exit from a pipe at the top.. A clarifier is a solids separator that uses time to let the solids settle at the bottom.. Solid filters filter out the suspended solids as well as the settable solids.. Bird netting as suspended solids filtration in the UVI system Screen filtration of Sieve filters is a method that is not widely used in aquaponics.. The water will flow over the screen, and the solids will stay on top while the water will drain to the other side.. If you are not sure about the quality of your fish food or the filters, take a look at the roots of your plants.. Get Started with Aquaponics

Your pond has the "pea soup syndrome"? A UV pond filter is a great solution to your problem. This article outlines all the basics & essentials you need to know before you buy one.

You still need a filter along with it.. So from now off on in this article, we’ll be referring to these UV pond filters as “UV pond lights”.. The obvious: The uv light is placed inline with the pump and the filter (either a mechanical or biological filter).. In fact, a lot of the biological filters (that have a uv light built in) place this uv light after the filter itself.. Any small rocks being sucked up by the pump and transported to the uv light can harm the quartz sleeve around the bulb.. Obviously, you need to clean the (mechanical or biological) filter from the waste, debris and dead algae.. So, it’s a good idea to clean this every year or so.. UV lights kills algae because water, with the free floating algae in it, passes over the uv lamp.. Some of these uv lights are submersible, and can be used under water or out of the pond.. My suggestion is to avoid looking at the light directly (even through the viewing window), avoid spending a lot of time looking for the blue light during the day (when it’s harder to see the light), and even use sunglasses to be on the safe side.

Here are five easy steps that walk you through choosing a filtration system for your saltwater aquarium.

Fortunately, there is a fairly simple method for selecting the right filter system for your tank.. You'll either choose a filter with a sump or one without a sump.. Models for everything from pumps, to wet/dry filters, to protein skimmers, to heaters, to algae, live rock and denitrators which have been designed specifically for sumps can be found.. If you have a basic idea of which types of filters you will using in your sump, you can get a feel for how much each filter will cost and what models will work for you by reading reviews reading reviews and compare prices on in-sump protein skimmers , a build-your-own wet/dry filter , submersible heaters , and submersible pumps (powerheads) .. Some equipment (pumps, skimmers, canister filters, UV filters) can be placed outside of the tank, connected to the tank with various hoses, pipes or overflows.. If you don't want to have a sump and you want to keep your tank (inside and out) as uncluttered as possible, remote mounted equipment may be the ticket for you.. Many In-Sump Protein Skimmers can be easily adapted.Most Canister Filters are designed to adapt easily for remote mounting.Many of the Combination Wet/Dry systems can be adapted, also.. Protein skimmers, water pumps, wet/dry filters and overflow supplied equipment can be found in a variety of styles, made by a number of manufacturers.. The types of equipment which can be mounted or used inside the tank is somewhat limited.. However, there are a number of filtration systems which are designed to use only In-Tank equipment and materials.. Here's the next fork in the road: Hang-On-Tank equipment vs In-Tank equipment.. Relying solely on In-Tank equipment limits your options for filtration equipment somewhat.. The Live Rock / Berlin Systems and the Live Sand Filtration & Jaubert or Plenum System setups have been around for quite a while and are among the favorites used by reef system purists.
