SPONGE CARTRIDGE FOR AQUAEL FILTERS FAN

AQUAEL sponges are made from carefully selected phenol-free sponge. They ensure effective mechanical filtration of the water,  retaining impurities and suspended particles visible to the naked eye. At the same time, they provide a substrate for the growth of nitrifying bacteria for biological filtration. 

For optimal performance, the cartridges should be replaced regularly. Maintenance should be done in a cup of aquarium water to maintain the biology that has grown on them.
