JW Pet Company Fusion 4 Power Filter for 15-40 Gallon Aquariums Aquarium Filter

The Fusion 4 Power Filter contains a revolutionary patented Up-Stream filtration system. The longer the filtered water stays in contact with the filtration media, the cleaner and purer the aquarium water. The Up-Stream water path insures maximum contact time with each of the three basic building blocks of aquarium filtration. The Fusion Power filter is a 3 Phase filter, designed to be an easy, simple way to pure, crystal clear water. Mechanical Filtration - FUSION Floss Cartridge traps dirt and debris. Biological Filtration - FUSION Ceramics Cartridge - beneficial bacteria are cultivated on the surface area of the porous Ceramic Modules and used to convert harmful ammonia and nitrites into harmless compounds. Chemical Filtration - FUSION Carbon Cartridge - Powerful FUSION Activated Carbon traps odors and removes discoloration leaving your aquarium with pure, crystal clear water...and healthy fish.  For use with 15-40 gallon aquariums, the Fusion 4 Power Filter is quiet, efficient, and simple to clean.
