QUIET & EFFICIENT: The Cascade 300 Power Hang-On Filter quietly delivers crystal clear water throughout the aquarium. This filter pushes water at 300 Gallons per Hour (GPH) for tanks up to 100 Gallons in size. It’s great for Freshwater and Saltwater aquariums.
The hang-on design is constructed for safe mounting. The lift tube extends between 8. 25” (min) and 12. 25” (max). Please be aware that the filter indeed does make some noise.

REVOLUTIONARY: The Cascade 300 Power Hang-On Filter features a Bio-Sponge cartridge that optimizes colonization of anaerobic bacteria, and is independent from the first stage filter media.
