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.

The Penn Plax Cascade Hang On Aquarium Filter features a revolutionary Bio-Falls Quad Filtration System to keep your tank clean and healthy. The polyfiber floss cartridge traps floating particulate matter while the activated carbon cartridge removes harmful chemicals, toxins, odors, discoloration and other contaminants from the water.

The external Bio-Falls wet/dry biological booster provides anaerobic bacteria for additional ammonia and nitrite removal while enhancing oxygen exchange for maximum water oxygenation. This hang on aquarium filter attaches easily to your tank by sliding over the edge of the glass. A leveling device keeps your filter in position and the self-priming intake tube has a built-in extendable stem to allow placement of the intake strainer close to the bottom of most aquariums. Filter includes an adjustable flow control knob to reduce filtration during feeding times or as needed, and the quiet and efficient motor is maintenance free.

Product Features

Higher Flow Rates

Aqueon filters have higher flow rates than the competition to ensure proper turnover for cleaner water and higher dissolved oxygen content, making fish healthier and more active.

Superior Biological Filtration

The patented biological grid has a large surface area to support more of the beneficial bacteria that eliminates ammonia and nitrates. A second wet/dry grid provides further biological filtration and oxygenation as the water returns to the aquarium.

Internal Pump Design

Since the filter pump is submersed in the aquarium, there is no need for priming at setup or when restarting the filter after cleaning or power interruptions. An internal pump also allows for virtually silent operation, continuous flow raters, less chance for leaks, and a much thinner profile.

Four Stage Advanced Filtration System

Stage 1: Dense floss removes particles and debris.

Stage 2: Activated carbon removes toxins, odors and discoloration.

Stage 3: Patented Bio-Holster removes toxic ammonia and nitrites.

Stage 4: Diffuser grid removes additional toxins while adding oxygen for more active fish. It also reduces splashing makes the return exceptionally quiet.
