6 in 1 Fish Tank Filters, Aquarium Sponge Internal Filter, Adjustable Flow Double Layer Sponge Fluidized Bed Filter for 5-75 Gallon Fish Tanks (No Pump Included)

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.

360° Outlet & Telescopic Riser: Swiveling outlet aims flow exactly where you need it. Extendable riser fits shallow or deeper tanks; run at the waterline for extra oxygen or submerge for a quieter return.

Quick Setup & Easy Cleaning: Tool-free assembly—just connect the airline. Rinse sponge and media in tank water (not tap) during water changes to preserve beneficial bacteria.

Broad Compatibility & Sizing Guide: Safe for freshwater or saltwater, shrimp and fry friendly; great for aquariums, turtle tanks, aquaponics, and hydroponics. One unit suits ~10–30 gal; pair units or use a stronger pump for tanks up to 75 gal.
