Aquatop’s FORZA Canister Filter Series is an innovative multistage filtration system. Each unit incorporates a patented, revolutionary one pump EZ Prime button so your canister filter begins cycling with just one pump! All models of the FORZA Canister Filter include mechanical and biological filtration media, along with all of the hardware required to get the unit up and running right out of the box!  As a bonus feature, all FORZA Models include a unique chemical filtration process which comes in the form of an integrated replaceable carbon canister cartridge. The replaceable cartridge is easily placed directly in the media tray so it’s no longer necessary to handle messy bags full of carbon. All FORZA Models also incorporate a number of additional features such as an optional surface skimmer on the inlet, a handle for easy lifting of the barrelhead, and a quick disconnect valve which is color coded; red for the inlet and blue for the outlet.

The FORZA Canister Filter Series with UV Sterilization (FZ7/FZ9/FZ13) delivers crystal clear aquarium water with the latest advancements in UV technology. In addition to biological, mechanical and chemical filtration, the FORZA UV Series includes UV Sterilization for added protection against harmful bacteria and unsightly algae. As an added innovative safety feature, the UV Models include a protective cover for the UV switch, a protective UV quartz tube guard, and should the canister move 30 degrees in any direction, the UV will automatically shut off and protect your system. Welcome to the new age of UV filtration!

How Does the UV Sterilization Work (FZ13/FZ9/FZ7)?
Unfiltered aquarium water enters the FZ UV Series Canister Filter and passes by the U.V. Sterilizing Bulb flowing down the stack of vertical cylinder cutouts to the bottom of the FZ UV Filter. Then water is pushed up through the filtration media compartments; the bottom compartment first, the middle compartment second, and the top compartment third. The filtered aquarium water then returns from the FZ Canister back into the aquarium.
