Round White Airstone (powder type)

A round air stone in powder form is used in aquariums to diffuse air into fine bubbles, enhancing oxygenation in the water. When connected to an air pump, the air stone releases tiny bubbles that increase the surface area for gas exchange, allowing more oxygen to dissolve into the water. This is particularly beneficial in densely populated tanks or during periods of high biological activity, helping to maintain healthy oxygen levels for fish and plants. The powder form allows for easy shaping and placement in various aquarium setups, and it can be replaced or refreshed as needed to ensure optimal performance.
