Aquarium Large Bio Sponge Filter Quiet Betta Fry Shrimp and Small Fish Foam Filter for Fish Tank Up to 60 Gallon

Air-Driven & Quiet: Connect to your air pump (not included) for gentle bubble-lift circulation and aeration—no harsh currents, ideal for bettas, shrimp, and fry.

3-in-1 Filtration: Double-layer sponge traps debris (mechanical), high surface area nurtures beneficial bacteria (biological), and upward flow improves surface agitation (circulation/oxygenation).

Two Sizes, Easy Sizing: Type A for tanks up to ~20 gallons; B for tanks up to ~40 gallons. For heavier bioloads or larger tanks, use a stronger pump or multiple units.

Easy Care, Longer Use: Rinse the sponge in tank water during water changes (not tap). Each unit includes 2 spare sponges for quick swaps and extended service life.

Shrimp & Fry Safe, Fresh or Marine: Fine-pore foam protects tiny livestock from being drawn in; compact footprint tucks into corners and works in freshwater or saltwater setups.
