Kaldness Moving Bed process, which had 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 buoyant. This near neutral buoyancy allows the media to circulate throughout the vessel with only a minimual water flow. This flow is created with your air pump and air stones or diffuser etc.

 

Maturing the Kaldness bio-media is important because a delicate eco-system is naturally developing for the bacteria involved in the nitrification process. Kaldness media provides the maximum active surface area for the bacteria to colonise, more than other types of static media. It is this process which removes harmful ammonia and nitrite from the water.

 

As the Kaldness moves within the filter, it causes the old dead bacteria on the outside to be displaced. This makes space for new younger heavier feeding bacteria to rapidly colonise. Within the wheel is a protected surface which enables colonies of bacteria to naturally follow their lifecycle, of maturing, dying and then fuelling the latter stages of the nitrification cycle. Kaldness has been designed to provide the best possible habitat for both young and mature beneficial bacterial colonies.

 

Unlike foam, matting, or other forms of static filtration media, Kaldness K1 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 disturbance of periodic cleaning, avoiding unnecessary loss of bacteria within the filter, 50 litres of K1 media will handle up to 250 grammes of food per day.
