air pump for aquarium #aquarium #fish

An air pump is useful for powering air stones (porous stones attached to the air pump with tubing) to supply supplemental aeration and circulation and to promote gas exchange (oxygen in, carbon dioxide out) at the water surface. Certain filters such as under-gravel filters are also powered with air pumps.
