Fish Tank Filter Detachable Filter with Air Stone, Aquarium Sponge Filter Suitable for 2-5 Gallon Tank (Air Pumps Not Included)

Before You Buy: This filter requires an air pump (not included). Best for 2–5 gal nano tanks.

Air-Driven, Ultra-Quiet: Bubble-lift circulation with the included air stone adds gentle aeration without harsh currents—great for bettas, shrimp, and fry.

Sponge + Air Stone Combo: Fine-pore sponge captures debris while the air stone produces smaller bubbles for better gas exchange and clearer water.

Detachable, Easy-Clean Design: Snap apart to rinse the sponge and body in tank water (not tap) and descale the air stone as needed—tool-free maintenance.

3-in-1 Filtration & Circulation: Mechanical trapping + biological surface area for beneficial bacteria, plus upward flow that breaks surface film and boosts oxygen.

Slim, Corner-Friendly Fit: Compact profile tucks against the glass; narrow intake slots help block large debris and protect small livestock—freshwater or marine use.
