This super biochemical sponge filter is a filter that keeps your aquarium always clean. The filter provides mechanical and biological filtration for easy aquarium maintenance. As a mechanical filtration, it use the air driven system to create suction, that allows the sponge to capture floating particles in the water and return filtered water to the tank. As a biological filtratration, harmful wastes are biologically transformed into a relatively harmless substance by aerobicbacteria that accumulates in the sponge. This kind of sponge is also suitable for Discus breeding tanks, small tropical fish tanks and fry stock tanks.To Use:-* Before use, soak the Bio-foam in aquarium water for 5 mins.* During maintenance, always rinse the Bio-Foam with drained out aquarium water only. No tap water or hot water should be used at all.* When re-using the Bio-Form, do squeeze the foam in the water to remove all trapped air bubbles. This will keep the filter stay submerged.* Suggest replacing the bio-foam every 6 months, to ensure the filtering effect as well as the growth of the nitrifying bacteria.
