Different filter cartridges perform various functions: 

Bio-cartridges with extractable filter pads offer the best colonisation conditions for the important purification bacteria. 

3D-active carbon cartridges, on the other hand, remove unwanted toxins and  should be used especially after medical treatment or initial set up of the aquarium.

• An additional after-sales product is the 3D-active carbon cartridge.
