Marineland Penguin Power Filters with Bio-Wheel feature complete, 3-stage filtration to keep their aquarium clear, clean, and healthy. Some of the new improvements to the Penguin filters include: A larger BIO-wheel that means more area for nitrifying bacteria to grow, keeping your aquarium totally free of harmful ammonia and nitrites. Increased flow rates maintain optimum water circulation and ensure proper BIO-wheel rotation. Adjustable water intake strainer allows you to take water from the bottom or mid-tank for the ultimate in complete circulation. The all-new cover design and sealed motor dramatically reduces water noise and vibrations while still maintaining optimum oxygenation. All Penguin Filter models still use the handy Rite-Size filtration media cartridges so changing the filter is a snap. Good for freshwater or marine aquariums.
Size: Filter is 5" x 5" x 7.5" high (Great for tanks up to 20 gallons).
