An essential tool for most types of aquariums, an aquarium pump aerates the water. In most large fish tanks, pH crashes and low KH levels can be dangerous. An air pump can help prevent these situations by pumping air bubbles into the tank, thereby agitating the surface of the water, which oxygenates it.

When searching for an aquarium pump, make sure you purchase one that is the right size and suits your tank's design.
