Nano Sponge Filter SF15
Sometimes the smallest filter makes the biggest splash... just without the splash.
The Nano Sponge Filter SF15 is the perfect filtration solution for compact freshwater aquariums where gentle water movement is essential. Designed for nano tanks, shrimp aquariums, fry grow-out tanks, betta setups, and juvenile axolotl enclosures, this compact sponge filter quietly keeps your aquarium clean while creating a safe, low-flow environment for delicate aquatic life.
Powered by an air pump, the SF15 provides excellent biological and mechanical filtration. Its high-quality sponge captures floating debris while offering a large surface area for beneficial bacteria to grow, naturally helping to convert harmful ammonia and nitrite into safer compounds.
Compact, reliable, and incredibly easy to maintain, the Nano Sponge Filter SF15 is an excellent choice for both first-time aquarium owners and experienced hobbyists looking for dependable filtration in smaller aquariums.

Care Tips
