Oxygenation: The bubbles produced by the air stone increase the surface area for gas exchange, allowing more oxygen to dissolve in the water and carbon dioxide to be released.

Circulation: The movement of bubbles helps circulate water in the aquarium, preventing stagnant areas and promoting an even distribution of heat and nutrients.

Aesthetic Appeal: Air stones can create an attractive visual effect with streams of bubbles rising through the water.

Noise Reduction: Compared to other types of aeration devices, air stones can operate more quietly, reducing the noise from air pumps.

Types and Sizes: Round air stones come in various sizes and materials, such as ceramic or mineral, to suit different aquarium sizes and setups.

Maintenance: Over time, air stones can become clogged with debris and minerals, reducing their efficiency. Regular cleaning or replacement is necessary to maintain optimal performance.
