Optimal Biological Filtration Using Sponge Filters
Sponge filters provide both mechanical and bio filtration, also, the air infusion chamber produces minute bubbles which increase the oxygen solubility
Easy to set up & clean: simply install an airline into the unit and turn on the air pump, simply rinse and squeeze sponge in tank water
Recommend tank Size: up to 20 gallon, 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
