Marineland Penguin Bio Power Filter 350

Using multistage filtration technology, Marineland’s Bio-Wheel Penguin Power Filter helps keep your aquarium crystal clear. It offers complete three-stage filtration for both freshwater and saltwater tanks. The Rite-Size filter cartridge traps debris and removes odors and discoloration, providing mechanical as well as chemical filtration. For maximum efficiency, fast-acting Black Diamond Premium Activated Carbon is used in each cartridge. An extra-large BIO-Wheel rotates to cultivate the beneficial bacteria that remove toxic ammonia and nitrates from the water. The BIO-Wheel features noise-reducing vented covers and adjustable intake strainers.
