Kaldnes K3 media is similar in application to Kaldnes 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.

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 etc.

What is meant by ‘self cleaning’ ?  Unlike foam, matting, or other forms of static filtration media, the Kaldnes K1/K3 media is designed to move freely within your filter. The constant chaotic movement of the air from your pump, causes the media to self clean and thus requires no maintenance. This allows the filter to reach optimum effectiveness without the disturbance of periodic cleaning, avoiding unnecessary loss of bacteria within the filter.
