Evolution Aqua K1 Media 25 Litres

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.

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.
