[Feature]This biochemical sponge filter keeps your fish tank clean at all times. It provides physical filtration and biological filtration for the fish tank, as a physical filtration: the biochemical cotton filter uses an air pump as a power source, using the suction provided by the air compression system, the biochemical cotton can capture the suspended matter in the water and return the filtered water Fish tank. As a biological filter: Hazardous waste is biologically decomposed by nitrifying bacteria that grow in the biochemical cotton and converted into substances that are harmless to fish.

[Usage] It is suitable for all kinds of ornamental fish breeding, breeding and the growth of juvenile fish, especially for colorful deification, small fish and fry.

[Note 1] 1. Disconnect all the plugs of the electrical aquarium appliances before putting hands into the water. 2. We recommended that air pump and other electrical aquarium devices, should be connected to correct voltage and power.

[Note 2] 1. Before use, soak the sponge in the fish tank water for about 5 minutes. 2. Do not use tap water or hot water to rinse the sponge, only use fish tank water. 3. When reusing the biological sponge, squeeze the sponge in the water to remove the air in the sponge, so that the sponge will remain submerged at the bottom of the tank. 4. It is recommended to change the sponge every 6 months to ensure the filtering effect and the growth of nitrifying bacteria.
