AQUANEAT Double Bio Sponge Filter for Fry, Betta, Shrimp, Nano Aquarium

The sponge filter provides both mechanical and biological filtration, and the air infusion chamber produces minute bubbles that increase the oxygen solubility. Setting up and cleaning the filter is easy: simply install an airline into the unit, turn on the air pump, and then rinse and squeeze the sponge in the tank water.

The recommended tank size for this filter is up to 55 gallons, making it an excellent choice for small fish like dwarf cichlids, guppies, and killifish, as well as for hatcheries, maternity tanks, and fry tanks. This is because the filter produces minimal current and has almost no way to suck the fish through it.

The filter dimensions are 6.5"L x 2.4"W x 9.5"H, and the package includes 4 sponge filters.

In summary, the sponge filter's dual filtration capabilities, easy setup and maintenance, and suitability for smaller fish make it a versatile and convenient option for aquarium owners. The included sponge filters ensure that the filter can be used effectively in a variety of tank sizes and configurations.
