Biofilter Media For Koi Ponds 

Biofilter Media For Koi Ponds , Koi fish are multi-coloured freshwater fishes that are simply gorgeous. They require high-quality water to survive in a pond.

We can build and install the necessary biofiltration systems for your pond according to its size and fish density. We use our custom-built biofilters and mechanical filters in aquaculture, public aquariums, koi pond systems, and other applications.

Any filter must have good quality media distributed properly, for it to perform well. This promotes the attachment and growth of various bacteria. While the water flows through the system, the media remains in place. The substrate or media used to provide the surface area is the heart of these biofilters.

Bacteria House

Bacteria House ceramic filter media is manufactured by heat-treating ceramic media for 60+ hours at 1300° C. This method of extreme heat conditioning breaks the inner bonds of the ceramic media and creates an exceptionally porous structure with a greater area for the colonisation of very large populations of bacteria within the expanded spaces.

It can also be used as a mechanical filtration medium. The highly porous characteristic of the media allows water to pass through without obstruction. This, in turn, aids in the rapid entrapment and decomposition of big organic materials.

What are the qualities of bacteria house media?

  • Excellent for the cultivation of nitrifying bacteria.
  • pH Balancing.
  • Aid in the purification of water, decomposition of harmful substances, and adsorption of impurities.
  • Increases water clarity naturally
  • Emits FAR infrared rays allowing more oxygen to be dissolved in the water

  • It is normal for ceramic dust to accumulate on its surface after transportation.
  • Thoroughly clean it with clean water before the first use.
  • If the bacteria house needs to be washed, do not use tap or boiled water after using it in the fish tank

Manufacture it similarly to a media house filter. The only differences are in its shape and cross-section area. The Bacteria House filter media emits FAR infrared rays, allowing increased levels of oxygen to dissolve in the pond water.

Bacteria House filter media produces FAR infrared rays, similar to those found in natural springs, with demonstrated significant health benefits.

Another advantage of the media is its ability to effectively de-gas koi pond water, which reduces the load on the bio-mass and makes the system use less KH than conventional filtration.

Pumice or Feather Light Stone.

Extremely microvesicular glass pyroclastic makes up pumice, featuring very thin walls of igneous rock bubbles. When volcanic gases dissolve in viscous magma, they generate bubbles. Pumice has a porosity of 64–85% by volume and can float for years on end before becoming saturated and sinking.

Pumice rafts flowed into the Indian Ocean for up to 20 years after the Krakatoa eruption, with tree trunks floating among them.

Black Filtration Foam

This biomechanical filter foam is the best to break down fish waste and fish feed leftovers. Its multi-porous design prevents clogs and gives bacteria plenty of surface area needed to adhere. The material comes in a variety of densities and thicknesses. It is durable and suitable for use in freshwater and marine water.

Cut it into any size as per your needs; it is lightweight and soft with excellent water permeability. Best to cultivate the required nitrifying bacteria for biological filtration. You can reuse these foams after cleaning. They may last up to several years before requiring replacement.

Some of the other commonly used biofilter media are listed below.

  • Filter Carbon/super sticks
  • Ceramic stones
  • Lava Rocks
  • Bio Balls-Various sizes are available
  • K 1-Kaldens Media
  • K 5 media
  • Jap Mats
  • Matala Mats
  • Ceramic Rings
