Aquarium Sponge Filter – Biochemical Bio Sponge for Air Pumps
Not every tank wants a current. Fry tanks, shrimp setups and hospital tanks all need filtration without the suction that pulls small animals against an intake, and an aquarium sponge filter is the standard answer. Driven by an air pump, it draws water gently through a biochemical sponge where bacteria break down waste, and there is nothing for a small fish or shrimp to be trapped against. This one suits air pump and skimmer arrangements.
Why fish keepers choose it
- ✔ Safe for fry and shrimp — no intake to be sucked against
- ✔ Biological filtration — the sponge hosts the bacteria that process waste
- ✔ Air pump driven — no impeller to fail or clog
- ✔ Gentle flow — suits bettas and other still-water fish
- ✔ Cheap to run — nothing to replace but the sponge itself

| Cleaning | Squeeze in tank water |
Is it right for your tank?
This aquarium sponge filter suits small and medium tanks where gentle flow matters more than turnover — a fry grow-out tank, a shrimp colony, a betta tank or a quarantine setup. It is not a substitute for a high-flow canister on a heavily stocked tank. Run it from an air pump and give it a week or two to build up bacteria before you rely on it.
Care
Squeeze the sponge out in a bucket of tank water during water changes, which clears the debris without destroying the bacteria. Never rinse it under the tap. Replace the sponge when it stops recovering its shape, and keep the air line clear so the flow does not drop unnoticed.
What’s in the box
1 x aquarium sponge filter with biochemical sponge and ABS body.
Filtering a small tank? Browse our filtration and water equipment, or pair this with the 3cm bio filter foam for a spare sponge stage.

Frequently Asked Questions
Yes, that is its main advantage. Water is drawn through the sponge rather than an open intake, so nothing small gets trapped against it.
Yes. It runs on air, so it needs an air pump or a skimmer that provides air flow to draw water through the sponge.
Give it a week or two to build up bacteria. Until then it is mainly mechanical filtration rather than biological.
Not on a heavily stocked tank. It suits small and medium tanks where gentle flow matters more than high turnover.
Squeeze the sponge in a bucket of tank water during water changes and never rinse it under the tap, which would kill the bacteria.
Once it stops springing back into shape, or when flow stays low even after cleaning. Replace it one at a time so the colony recovers.
