The Tetra Whisper 40i Internal Filter for aquariums is the ultimate in quiet, convenient 3-stage filtration. This submersible filter mounts on the inside of the aquarium, rather than hanging from the outside, making it possible to place the tank flush against a wall and easily hide with tank décor.

For 20-40 gallon tanks.Since 1951, Tetra has developed the
