These filters are mounted 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 adjust easily to high or low water levels with mounting suction cups and brackets. Each filter comes with one pre-assembled Whisper Bio-Bag filter cartridge. This filter has a filtration capacity of up to 30 gallons.
