Sponge Filter (Up to 10 Gallon Aquariums)

Small Sponge Filter – Quiet Air-Driven Filtration (Up to 10 Gallon Aquariums)

This small sponge filter is designed for nano aquariums up to 10 gallons, providing gentle and effective filtration without stressing fish or shrimp. The compact round shape fits easily in small tanks while offering excellent biological and mechanical filtration.

Made with high-density sponge material, it traps debris and supports beneficial bacteria that help keep ammonia and nitrite levels stable. Powered by an air pump (not included), this filter runs quietly and creates soft water movement—perfect for bettas, guppies, shrimp, fry, and other small freshwater fish.

In my opinion, this is one of the safest filters you can use in a small tank. No motors, no strong suction, and almost zero maintenance headaches.
