Hang this mighty little filter inside your aquarium, supported by the tank rim, or attach it to the side using suction cups--Whisper In-Tank Filters are powerful and versatile. The submerged motor provides quiet and powerful filtration, making the filter useful for filled aquariums or low-water environments such as turtle tanks. Its position inside the tank allows aquariums to be moved flush to the wall, and positioning on a side allows a full view of your beautiful fishy friends without the distraction of filter boxes or power cords. Full two year warranty included. Made in China.
