Product Description

Pond Filter Media
Evolution Aqua Kaldnes K1 Media 25 Litres
Code: MEDIA25L


K1 media is engineered in a wheel shape and is slightly positively buoyant. This near neutral buoyancy allows the media to circulate throughout the vessel with only a minimal water flow. This flow is created with your air pump and air stones or diffuser etc.

How it works?
Maturing the K1 bio-media is important because a delicate eco-system is naturally developing for the bacteria involved in the nitrification process. K1 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.

How it is different to other media?
As the K1 Media 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 life cycle, of maturing, dying and then fuelling the latter stages of the nitrification cycle. K1 Media has been designed to provide the best possible habitat for both young and mature beneficial bacterial colonies.

What is meant by 'self cleaning'?
Unlike foam, matting, or other forms of static filtration media, 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 the 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.
