What is a biological filter in a pond?

Biological filters are positioned to create the beginning of the waterfall in your pond. The filter uses bacteria to break down pond wastes, converting them into less harmful compounds that can be used as aquatic plant fertilizers. Water enters the biological filter from the skimmer via flexible pipe located near the base of the unit.

How do pond water filters work?

Biological filters use bacteria to break down pond wastes, converting them into less harmful compounds that can be used as aquatic plant fertilizers. Mechanical filters trap and remove debris and sediment. Water sterilizers pass water through a tube that houses an ultraviolet bulb, killing living microscopic particles in the water.

What are the different types of pond filters?

Mechanical filtration is a basic type of filtration that it is a component that is found in almost every pond filter, and it helps improve water quality immensely. Biological filtration within a pond filter houses the beneficial bacteria, which processes the organic waste material.

What are the benefits of pond filtration?

Another important component to pond filtration is the use of plants. Many gardeners add a pond to their landscape for the variety of aquatic plants available, and while their beauty is certainly an aesthetic asset, a critical benefit is the work these plants do to help filter the water.

How does a pond bio filter work?

A pond pump pumps water through the biological filter. This biological filter contains bacteria which convert waste materials in carbon dioxide. Carbon dioxide, in turn, is pumped into the pond and serves as fertilizer for the plants in the pond therefore this is called the biological cycle of a pond.

How does a bio filter work?

Biofiltration is a pollution control technique using a bioreactor containing living material to capture and biologically degrade pollutants. Common uses include processing waste water, capturing harmful chemicals or silt from surface runoff, and microbiotic oxidation of contaminants in air.

Do I need a bio filter for my pond?

Because living bacteria are the main filtering component this filter is called a biological filter. All fish ponds must have a well functioning biological filter for the safety of the fish. The bacteria live on all wet surfaces in the pond. This means that all ponds already have some kind of biological filter.

Is biological filter necessary?

The good news here is that you don't need to buy a biological filter. You see, the filter is natural. Naturally occurring bacteria will begin to grow and multiply in your tank, eating that waste and converting it into nitrate. All you need to do is give it a place to live.

What is one drawback or disadvantage to using a bio filtration process?

However, biofiltration does have some drawbacks, such as the need for complex water and air distribution systems, backwash requirements, occasional massive biofilm sloughing and a high nitrite residue in the effluent (Buttiglieri et al., 2005).

How long does it take for a bio filter to work?

This can take 1 to 6 weeks for this bacteria to become established in an aquarium. These bacteria will convert ammonia into nitrite (NO2). Although less toxic than ammonia, nitrite will still harm your fish.

How much Bio filter media do I need?

Each 1000g of FilterPlus is enough bio-media to filter a heavily stocked 55 to 75 gallon aquarium, or a medium-stocked 100 gallon aquarium. We recommend 75 to 100 grams per 10 gallons for medium-stock level, and 150 to 200 grams per 10 gallons for heavy-stock level.

What happens when water is pumped into the bottom of the filter?

Water is pumped into the bottom of the chamber, causing the filter media to fluidize and expand while swirling inside of the chamber. This constant motion of the filter media is what distinguishes fluidized bed filters from traditional biological filters. The biological filtration process takes place as the bacteria housed within ...

What is a fluidized bed filter?

Fluidized bed filters are one of the newer advancements in filtration technology. The main difference is that with regular biological pond filters, the filter media is stationary inside the filter. In the case of fluidized bed filters, a special type of granular media is used which occupies the bottom portion of a flooded chamber. Water is pumped into the bottom of the chamber, causing the filter media to fluidize and expand while swirling inside of the chamber. This constant motion of the filter media is what distinguishes fluidized bed filters from traditional biological filters. The biological filtration process takes place as the bacteria housed within the granular media interacts with the flowing water. The water eventually makes its way through the abrasive filter environment, to the top of the chamber where the water is returned by gravity to the pond.

How does a gravity fed koi pond work?

Gravity fed filters, like the name suggests are fed by gravity via a bottom drain at the bottom of the pond. The top of the filter is placed exactly level with the top of the pond, such that gravity will naturally equalize the level of the water in the filter to be the same height as the rest of the pond. The last chamber of the filter contains a submersible pump which pumps filtered water back into the pond. Multichamber filters work well due to the multiple stages that the water must pass through before finally being returned to the pond. Each stage contains a unique filtration method, methodically refining the water quality further as each stage passes. The first stage of such systems is often a Vortex filter, which filters out heavy solids including fish waste, leaves, and hair algae.

What is gravity return pond filter?

Gravity return filters have been around for sometime and are one of the most cost effective biological filtration systems available. Water from the pond must be pumped into the inlet of the gravity return biological pond filter using either a submersible or external pump. The water then flows through the filter, ...

Why do pond filters have to be elevated?

Because of this, the filter must be elevated above the surface of the pond for gravity to pull water from the filter back into the pond. This feature happens to also be one of the complaints associated with gravity return filters; they must be elevated above the pond level, and are therefore harder to conceal. A pressurized pond filter.

What is a biological pond filter?

A quality biological pond filter is an essential piece of equipment necessary to any well-designed filtration system. Biological filtration is a broad term referring to the means of housing beneficial bacteria that are able to clean pond water at a molecular level. In a natural stream or river, bacteria colonize on the stones and pebbles at the bottom of the stream, which naturally break down toxins as the water flows overtop. It is this natural process that manufactured biological filters attempt to emulate. However, instead of cultivating bacteria at the bottom of the pond like in nature, for ease of maintenance, bacteria are colonized in various types of filter media, which are stored in a filter housing outside of the pond. The water is forced to flow through the filter via a pumping system, or a gravity fed system.

Why do we need a biofilter for ponds?

One of the main uses for a biological pond filter is to convert harmful ammonia, which is toxic to fish and other life, into nitrite and then eventually nitrate. Amonia is naturally produced from fish waste and other decaying matter in a pond. Although nitrate is non-toxic to koi and other pond fish, ...

Why Do You Need a Pond Filter System?

A pond filter helps keep the pond ecosystem healthy and thriving. It helps create an environment that is suitable for beneficial bacteria to thrive, which helps accelerate the nitrogen cycle. Ultimately, this creates an environment that is habitable for fish and other aquatic organisms.

What is biological filtration?

Biological filtration within a pond filter houses the beneficial bacteria, which processes the organic waste material. Uneaten food, fish waste, and other nutrients in the water turns into ammonia and nitrites. Accumulation of ammonia and nitrites is dangerous to fish, and it will kill them at high concentrations. The beneficial bacteria in the biological filtration will help process the ammonia and nitrites into nitrates, which are less harmful to the fish. This is part of the nitrogen cycle. Biological filtration is especially important if your pond is well-stocked with fish. Keep in mind that a biological filter requires time to get established. This is because there are no beneficial bacteria in the filter when the filter is installed initially. The biological filter simply provides the necessary surface area for the beneficial bacteria to grow on. 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. Popular media for biological filtration include plastic bio-balls and ceramic rings. Biological filtration is one of the most important functions of a pond filter.

How does a pond filter work?

Mechanical filtration within a pond filter collects small and large pieces of debris in the water. The water pump moves water through the filter media, which catches debris such as leaves and uneaten food particles. Filter media may consist of multiple different material such as brushes and sponges. The largest debris may be collected by a pre-filter before it goes through the filter media as well. 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. Mechanical filtration is a basic type of filtration that it is a component that is found in almost every pond filter, and it helps improve water quality immensely.

How to choose a pond filter?

When choosing the right filter size for your pond, choose a filtration system that has sufficient flow rate. Filtration flow rate is commonly measured in gallons per hour (gph). The rule of thumb is to install a filter with a gph rating of 1.5 times the number of gallons in your pond. For example, if you have a 100 gallon pond, get a filter that is rated for 150 gph.

Why do ponds need a filter?

The primary function of a pond filter is to keep the water oxygenated, which helps create a suitable environment for beneficial bacteria. Without the beneficial bacteria, the waste that the fish produce will accumulate as ammonia in the pond very quickly. This is the reason why a stagnant pond without a proper filtration system will not be able to support very many fish.

What are the different types of pond filters?

Some of the most common types of filtration in a pond filter are, mechanical filtration, biological filtration, and UV filtration.

How does UV light kill algae?

UV pond filtration, or UV sterilization, in kills off algae and other free-floating microorganisms. The powerful UV light will kill the algae, so if your pond is struggling with green water, this may help. However, keep in mind that types of algae that are not free-floating, such as string algae, will not be affected. In addition, microorganisms that are killed by the UV light may include both good and bad bacteria. Therefore, it is important to consider the advantages and disadvantages when using a UV filter. Make sure the biological filtration system is well established before using a UV filter. In some cases, it may be better to turn on the UV filter only when necessary.

How to keep pond water quality high?

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. Add the remaining components of plants, fish, aeration, rock, and gravel, and you’ll find greater success in maintaining clean and clear pond water.

How are nitrates removed from ponds?

Nitrates are then removed from the pond by another biological filtration method known as de-nitrification. This process occurs only in anaerobic (without oxygen) areas of the pond. That’s why it’s not necessarily bad for some areas of the pond to experience minimal water flow (such as on the bottom of the pond, under an inch or so of gravel). The bacteria that live in this area of the pond turn nitrates into nitrogen gas, which is released into the atmosphere. Nitrates are also absorbed by aquatic plants and algae during their growth processes. A pond without aquatic plants will prove to be a maintenance nightmare.

How does a pond skimmer work?

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. The pond water then travels through the plumbing buried underground, up to the biological filter where it’s further treated before re-entering the pond.

Why is surface area important for a pond?

For any biological filtration to work, there literally needs to be billions of bacteria working to purify the water. They prefer to anchor onto things, which is why surface area is so important. More surface area means more bacteria, and more bacteria means better biological filtration. Surface area is provided by filter media, rocks, and gravel. A pond with gravel on the bottom will contain more surface area for bacteria, as opposed to a pond with exposed liner on the bottom.

What is the purpose of mechanical filtration in ponds?
