100-00-314
Kaldness K3 media is similar in application to Kaldness K1 media, in that the constant chaotic movement of the air from your pump causes the media to self-clean and thus requires no maintenance. K3 media is different than K1 media, as it is designed to be used in the retrofitting of existing filters bays as the slightly larger media size allow for easier configuration and control. Kaldness Moving BedTM 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.
