The Emperor Power Filter Pro Series delivers continuous uninterrupted 3-stage filtration driven by its revolutionary dual impeller design. The main impeller drives water directly to and through the mechanical and chemical filtration stages producing a specific amount of gallons per hour depending on the size of filter you choose. The secondary impeller then pressurizes the filtered water through the spray bars powering the extra large bio-wheels. This feature is unique to the Emperor Power Filters.
Biological filtration is provided by the revolutionary Bio-Wheel - removing toxic ammonia and nitrites

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.In-Tank 10i - Up to 10 Gal, 90 GPH. Uses Medium Bio-Bag Measures 4.2 x 4 x 8 inches
