Tetra Whisper In-Tank Power Filters provide the ultimate in convenience and quiet. 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.
- Motor is under the water for extremely little noise
- Functions in as little as 2 inches of water
- Includes one pre-assembled Whisper Bio-Bag filter cartridge
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.
Whisper In-Tank filters adjust easily to high or low water levels with mounting suction cups and/or clip. Each filter includes one pre-assembled Whisper Bio-Bag filter cartridge and mounting clip.
