Sell AQUARIUM BIO SPONGE Filter NO.2838 XL best price

This super biochemical sponge filter keeps your aquarium always clean. The filter provides mechanical and biological filtration for easy aquarium maintenance. As a mechanical filtration, it uses 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 filtration, harmful wastes are biologically transformed into a relatively harmless substance by aerobic bacteria that accumulates in the sponge. This kind of sponge is also suitable for Discus breeding tanks, small tropical fish tanks and fry stock tanks.
