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 internal sponge optimizes the colonization of beneficial anaerobic bacteria while removing ammonia and nitrites.
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.
The Penn Plax Cascade Hang On Filter delivers up to 200 gallons of water per hour and is suitable for fish tanks up from 35 to 55 gallons in size.
It measures 10 inches high by 7.5 inches wide by 5 inches deep and is suitable for both freshwater and saltwater tanks.

The Cascade Hang-On Aquarium Filter comes with Bio-Floss and Activated Carbon cartridges and is Ready-to-Use.

Please Note:
For heavily stocked aquariums or turtle tanks, we recommend purchasing one size larger than the size of your tank requires as the additional waste output generated by these aquariums puts additional stress on the filtration system.
