Aquatop PowerFlow Internal Sponge Filter 2 – for Medium Aquariums, 70 GPH

The Aquatop PowerFlow PSF-2 Internal Sponge Filter brings modern convenience to one of the aquarium hobby's most trusted filtration methods. By incorporating a quiet, energy-efficient water pump directly into the filter body, the PSF-2 eliminates the need for noisy external air pumps and airline tubing while delivering reliable mechanical and biological filtration in a compact, easy-to-maintain design.

Engineered for medium-sized aquariums, breeding systems, shrimp colonies, quarantine tanks, and community aquariums, the PSF-2 combines a high-density sponge with integrated biological filter media to create a complete filtration solution. The sponge captures suspended debris and fine particulate waste while providing an excellent surface for beneficial nitrifying bacteria. Additional biological media located beneath the sponge further supports the nitrogen cycle, helping maintain stable water quality and a healthier aquatic environment.

Delivering a powerful yet gentle 70 gallons per hour, the PSF-2 provides excellent water circulation without producing excessive current. This makes it well-suited for aquariums housing community fish, livebearers, dwarf cichlids, shrimp, and many other species that benefit from efficient filtration combined with moderate water movement.

Routine maintenance is quick and economical. The reusable sponge can be rinsed in aquarium water during regular cleaning, preserving beneficial bacteria while restoring filtration performance. The integrated pump requires minimal maintenance and operates quietly, making the PSF-2 an excellent choice for living rooms, offices, bedrooms, classrooms, and fish rooms.
