Air Pump Driven, Adjustable Flow: Connect to your air pump (not included) with the included hose and inline air valve to fine-tune bubbles and flow. Choose a stronger pump for larger tanks.

6-in-1 Multi-Stage Filtration: Double-layer threaded sponge traps debris; fluidized moving-bed media and ceramic bio-balls boost nitrifying bacteria; built-in aeration, circulation, and surface agitation improve water clarity and stability.
