Pawfly Mini Aquarium Sponge Filter for 5-20 Gallon Fish Tanks

The small, medium, and large sponge filters offer versatile filtration options for your aquarium needs. Designed to effectively trap debris, food residues, wastes, and other impurities, these mini aquarium sponge filters help keep your water clean and clear.

Each size of the sponge filter comes with its own set of features and specifications. The small sponge filter, measuring 2.13 x 2.4 inches, is suitable for 5-gallon tanks and can handle an air flow rate of up to 9.5 GPH (0.6 L/min). The medium sponge filter, measuring 3.2 x 2.2 inches, is suitable for 5-20 gallon tanks and can handle an air flow rate of up to 12.5 GPH (0.8 L/min). The large sponge filter, measuring 4.1 x 2.2 inches, is suitable for 20-40 gallon tanks and can handle an air flow rate of up to 20.5 GPH (1.3 L/min).

The sponge filters are powered by air pumps, with the small filter requiring a pump less than 2W, the medium filter requiring a pump less than 4W, and the large filter requiring a pump less than 5W. These air-powered aquarium filters produce a cascade of dense bubbles in the water, greatly promoting oxygen circulation to keep your fish healthy and thriving.

Mechanical filtration is provided by the sponge filter's ability to trap debris, food residues, and other impurities, preventing them from entering the aquarium and keeping the water clean. Additionally, the inclusion of mini filter balls on the bottom of the sponge filter helps block large particles and accumulate beneficial elements, providing biological filtration to fully remove excess harmful substances.

The sponge filters are easy to clean, with the submersible design allowing for easy detachment for maintenance. Rinse the sponge every 2 to 4 weeks using only aquarium water, and avoid soaking or washing it in tap water. Replace the white sponge every 2-3 months to ensure optimal filtration performance.
