K1 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 buoyant.
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 etc.
