There are many different uses for air pumps: running air driven protein skimmers, running ozonizers, and adding bubbles to an aquarium via an air stone. Having a well-aerated tank will help stabilize pH level and provide the necessary oxygen for respiration. Also, battery-operated air pumps are available to help keep your aquarium oxygenated during a power failure.
