This complete dual sponge filter kit provides reliable mechanical and biological filtration for freshwater aquariums up to 55 gallons. Ideal for betta tanks, shrimp tanks, fry grow-outs and nano setups, the double-sponge design increases filtration surface area while keeping water flow gentle and safe for small fish.

Easy to install and maintain—simply connect the included airline tubing to your air pump, attach the check valve to prevent backflow, and secure the filter with suction cups. Rinse the sponge in tank water during water changes to keep performance high.
