Marineland Marineland Magniflow Canister Filter 220 The revolutionary design of the new Marineland Magniflow Canister filter forces water to pass through the filter media trays and not around them. With virtually no bypass and a three-stage filtration process, only sparkling-clean water can recirculate into your tank-regardless of size or type of aquarium. The key to this process is our special internal design and three-stage approach that passes the water through a series of specialized filter media. It's a design that delivers the best available technology in mechanical, chemical and biological filtration... and it's a design that is unmatched for capturing particulates. Filters 220 GPH up to a 55 gallon tank
