Tetra Whisper 20 Aquarium Air Pump gives your aquarium a big advantage. It creates proper gas exchange by increasing water circulation and surface area so fish can swim happily with the correct amount of oxygen in the water. The air pump also adds a great look with the underwater bubbles it produces. With a shape that flattens sound frequencies, this pump makes minimal noise yet still achieves maximum airflow. It features sound-dampening chambers that are specifically designed for this model. It even has a suspended motor and rubber feet so it won't vibrate on surfaces. This air pump is ideal for up to 20 gallon aquariums.
