Aquarium Bio Sponge Filter up to 60 Gal Breeding Fry Betta Shrimp Fish Tank

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. Sponge filters provide both mechanical and biological filtration. Most sponge filters are reasonably efficient filters for small volume tanks. These filter are excellent for small size fish like 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. Also, the air infusion chamber produces minute bubbles which increase the oxygen solubility.

This sponge filter provides both mechanical and biological filtration for your tank. promotes gas exchange process and increases dissolved oxygen level in water. It's easy to set up. Just install an airline into the unit and turn on the air pump ( air pump and airline not included). The sponge traps waste particles mechanically and cleans the water without trapping baby fish.
