Filter Media for Koi Ponds
The filter media used in a koi pond needs to support a healthy colony of bacteria, to deal with the waste (ammonia) produced by fish. Our range of filter media is chosen for it's high surface area, ease of use, and durability.
What's the best filter media?
There is no one best filter media, but a GOOD filter media will have a high surface area to volume ratio. The higher the ratio, the higher the (theoretical) feed rate will be for a given amount of filter media. Some media, like Evolution Aqua K1 Filter media gives a rating for feed rates which can be useful when comparing filter medias. When choosing a filter media, you have to considor what filter system you are using too. A bakki shower for example works best with a highly pourous filter media, such as our Sakura Far Infrared Shower Filter Media, or Momotaro Bacteria House Media. Evolution Aqua K1, K1 Micro, Oase Hel-X, and ECO Pond Chip are more suited for moving bed filters, which offer a very efficient way of dealing with the ammonia produced by the fish. Moving bed filters offer a high oxygen environment, and the continous, mostly random water movement in a moving bed filter keeps the chamber almost self cleaning.
