Recommend Tank Size: Up to 60 gallons, excellent for small size fish like betta, dwarf cichlid, guppy, killifish etc, or for hatcheries, maternity tanks, and fry tanks, as the filter produces minimal current and has almost no way to suck the fish through the filter. DIMENSION: 4.5"D X 8.0"H. Package includes: 1 PC of sponge filter. *This filter fits standard 3/16” diameter airline tubing. How Does It Work? A sponge filter uses bubbles of air from an external air pump, or an integral water pump to draw water through the sponge. As water is drawn out through the lift tube or pump, it is replaced by water entering the sponge.The sponge is a mechanical filter and the surface of all the bubbles or pockets in the sponge provide a bed for the bacteria of a biological filter. What Maintenance Does It Require? The sponge will need to be rinsed every time it becomes dirty, about once every 2 to 4 weeks. It’s helpful to reserve the beneficial bacteria by washing the sponge gently with water from the fish tank instead of tap water. So it is recommended to replace the sponge once every three to six month or when the sponge gets worn out.
