Dual-Sponge Aquarium Filter, Unit/Media Options

Add an air-driven sponge-filter arrangement to a suitable aquarium. Choose a complete small or large unit, or the replacement-media option for an existing filter.

• ✅ Provide filter surface - the sponge supports an established biological filtration process.
• ✅ Circulate through an airlift - the unit uses a matching external air source.
• ✅ Replace media separately - sponge/media choices differ from the complete unit.

Match the Filter and Air Supply

Check the unit dimensions, air connection and airflow requirements around the tank's inhabitants. Fit the suction cups on a suitable clean surface and allow the biological filter to establish.

Do not assume the model size is a tank-volume rating. Maintain media according to the aquarium plan and avoid replacing all established biological surfaces at once. The air pump and aquarium are not included.
