Aquarium air pumps are essential for maintaining a healthy fish tank. General information on their functions and types, or help researching a particular model, can be provided. Their main purpose is to increase dissolved oxygen, supporting fish and other aquatic animals as well as beneficial bacteria in the filtration system. Bubbles disturb the water surface to promote gas exchange, releasing carbon dioxide and introducing oxygen. Water movement helps distribute heat, nutrients and oxygen evenly. Air pumps also operate air stones, moving ornaments such as opening treasure chests, and sponge filters.
