The Hygger Aquarium Cylindrical Sponge Filter, Small delivers powerful 3-in-1 filtration"”mechanical, biological, and aeration"”while staying whisper-quiet and easy to maintain. Perfect for shrimp, bettas, fry tanks, nano aquariums, and large tanks for supplemental filtration, it combines a high-density sponge with a ceramic bio media chamber to keep water clean, stable, and well-oxygenated. Fits aquariums up to 20 gallons. An air pump is required for use but is not included.
3-in-1 Filtration System: Mechanical + Biological + Aeration. The sponge traps debris and particles, while ceramic bio media supports beneficial bacteria to remove harmful ammonia and nitrites. Rising bubbles from the air pump simultaneously oxygenate the tank.
Features:
Upgraded Biochemical Sponge: High-density, non-clogging sponge captures waste, uneaten food, and fish debris without harming delicate fish or shrimp.
Built-In Bio Media Chamber: Strengthens biological filtration with included ceramic media, improving water clarity and long-term stability.
Quiet & Energy Efficient: Silent operation powered by an external air pump (not included). Ideal for bedrooms, offices, and breeding setups.
Easy to Assemble, Clean & Maintain: The filter disassembles quickly for maintenance. Simply rinse the sponge in tank water"”no complicated steps.
How It Works:
The air pump pushes air through the air stone.
Rising bubbles create suction through the sponge.
Sponge filters debris (mechanical filtration).
Water passes through ceramic media (biological filtration).
Clean, oxygen-rich water rises back into the tank.
