Replacement filter foam for Marineland Canister 360 provides a large surface area for trapping particulate matter for optimal mechanical filtration. Also provides ideal area for bacteria colonization. Note: Aquarium water is drawn into the canister and through a succession of stacked media trays for full contact filtration with virtually no bypass. When it’s time to service your C-Series canister filter, all you do is push a lever, turn the key, and lift out the easy-access media trays.
