Super efficient media for trapping waste particles.
The media is engineered in a wheel shape and is slightly buoyant. This near neutral buoyancy allows the media to circulate throughout the filter with only minimal water flow.This flow is created with your air pump and air stones or diffuser etc.Each piece of K1 is approximately the size of a 5p piece.
25 litres of K1 will handle up to 125 gramme of food per day
Can be retro fitted to existing filters (larger K3 media is usually better for this process)
