Tetra Whisper Internal Filter 10 To 30 Gallons, For aquariums, In-Tank Filtration With Air Pump

For the ultimate in convenience and quiet, choose a Whisper In-Tank Filter. These filters mount on the inside of the aquarium, rather than hanging from the outside -- making it possible to place the tank flush against a wall. In-Tank Filters are unusually quiet, since the motor is under the water. Offering the same quality and performance as an external filter, the Whisper In-Tank Filter will function in as little as 2 inches of water -- making it ideal for turtle tanks, or for creating a waterfall inside the tank.The Whisper In-Tank filter features adjusts easily to high or low water levels with mounting suction cups and/or bracket. Each filter comes with one pre-assembled Whisper Bio-Bag filter cartridge.
