Penn-Plax presents the Cascade 200 Power Hang-On Filter. This filter quietly delivers crystal clear water, and pushes water at 185 Gallons per Hour (GPH) for tanks up to 55 Gallons in size. It’s great for Freshwater and Saltwater Aquariums. Accommodating: The adjustable flow knob allows for increased or decreased water flow at will, which is extremely helpful during feeding times, or use it as needed.

The hang-on design is constructed for safe mounting. The lift tube extends between 7” (min) and 11” (max). Extremely Beneficial: This Cascade filter utilizes disposable, double-sided media cartridges that contain Activated Carbon and Poly Fiber Floss. The included cartridge traps floating particulate matter, removes harmful chemicals and toxins, clears up discolorations, and reduces foul odors from your aquarium’s water.

Revolutionary: The Cascade 200 Power Hang-On Filter features a Bio-Sponge cartridge that optimizes colonization of anaerobic bacteria, and is independent from the first stage filter media. In addition, our Bio-Falls system enhances water oxygenation, and aids with removing ammonia and nitrate.

Overall Measurements: 6. 75” (H) x 7. 25” (W) x 4. 75” (D).
