Tetra Whisper Internal Power Filter 40i

Tetra Whisper In-Tank Power Aquarium Filters offer super quiet power filtration that is easy to conceal within your aquarium. As versatile as they are powerful, these filters are ideal for low water level environments such as turtle tanks. The position it takes inside the tank allows aquariums to be moved flush to the wall, and positioning on a side allows a full view without the distraction of filter boxes or power cords.
