For the ultimate in convenience and quiet, select a Whisper In-Tank Filter. These filters mount at the inside of the aquarium, quite than hanging from the out of doors — making it imaginable to place the tank flush against a wall. In-Tank Filters are unusually quiet, for the reason that motor is under the water. Offering the same quality and performance as an external filter, the Whisper In-Tank Filter will function in as low 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. Every filter comes with one pre-assembled Whisper Bio-Bag filter cartridge.
