Pawfly Mini Aquarium Sponge Filter for up to 5 Gallon Fish Tanks

The mini aquarium sponge filter can effectively trap debris, food residue, wastes or other impurities in the water, preventing them from entering the aquarium to keep the water clean. The build-in mini filter balls are helpful for blocking large particles in the water and accumulating beneficial elements, providing biological filtration to fully remove excess damaging substances.

Measuring 2.13" W x 2.4" H, the small internal filter is suitable for fish tanks up to 5 gallons, making it ideal for the breeding and feeding of various ornamental fish, shrimp or fish fry. The detachable submersible filter requires an air pump of less than 2 W, with a jetting volume of the air stone at 0.6 L/min. The bio sponge filter with air stone can produce a cascade of dense bubbles in the water, greatly promoting oxygen circulation to keep your fish healthy.

For the medium sponge filter, the dimensions are 3.2" x 2.2", suitable for 5-20 gallon tanks. The large sponge filter measures 4.1" x 2.2" and can be used in 20-40 gallon tanks. The maximum air flow rates for the small, medium, and large filters are 9.5GPH (0.6 L/min), 12.5GPH (0.8 L/min), and 20.5GPH (1.3 L/min), respectively. The required air pumps for the medium and large filters are less than 4 W and 5 W, respectively.

The bio sponge filter can be easily detached for cleaning. It is recommended to rinse the sponge every 2 to 4 weeks using aquarium water only, and to avoid soaking or washing it in tap water. The white sponge should be replaced every 2-3 months.

With a customer review rating of 4.6 out of 5 stars (based on 19 reviews), the small, medium, and large sponge filters are priced at $7.99, $9.99, and $12.99, respectively.
