- Makes Your Nexus 220 Filter ' Hands Free'
The Kaldnes Moving Bed process has been scientificallly tried & tested in fish farming & waste water treatment for over 10 years. The media is engineered in a wheel shape & 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 & air stones or diffuser etc.
