Ocean Free Junior Jumbo Sponge Filter for up to 680l Tanks

This super biochemical sponge filter is a filter that keeps your aquarium clean. The filter provides mechanical and biological filtration for easy aquarium maintenance. Mechanical filtration, 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 filtration, harmful waste is 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.
