K1 Kaldness Medium

K1 Kaldness Medium is the best filter media you can use in a moving bed filter. In a static filter, it certainly works well too.

Maturation of the K1 Media bio-medium is important because a delicate ecosystem naturally develops for the bacteria involved in the nitrification process. K1 Media provides maximum active surface area for the bacteria to colonise, more so than other types of static media. It is this process that removes harmful ammonia and nitrite from the water.

As the K1 Media moves in the filter, the old dead bacteria on the outside are displaced. This makes room for new, younger, heavier-feeding bacteria to rapidly colonise. Inside the wheel is a protected surface that allows bacterial colonies to naturally follow their life cycle of maturing, dying off and then feeding the final stages of the nitrification cycle. K1 Media is designed to provide the best possible habitat for both juvenile and adult beneficial bacteria colonies.
