We carry a wide variety of replacement filter media for your Koi pond.Bacteria convert harmful by-products from aquatic animals into less harmful nitrates.This process occurs naturally in nature's lakes and streams. In a Koi pond these bacteria are found on the walls of our ponds. They also can be found on the inside walls of the pond plumbing, attached to the skimmer basket, and on the rocks that form a waterfall.
The reason it is important to consider what filter media to use when we build biological filter systems, is to increase the available surface area for these bacteria to colonize.The important consideration is to keep the pollutants and unwanted debris out of our ponds, while keeping the beneficial bacteria in our systems. If you have any questions regarding the proper media, feel free to contact us for help. Kaldnes is the new boy on the block.
Kaldnes Moving Bed process, which has been scientifically tried and tested in fish farming and waste water treatment for over 10 years, is now available for fish keepers and is exclusively distributed worldwide by Evolution Aqua.
The media is engineered in a wheel shape and is slightly positively bouyant.This allows a small amount of water flow to circulate the media throughout the vessel.This flow is created with your air pump and air stones or diffuser.
