Aqua One Air Stones enhance your aquarium in multiple ways. They ensure proper oxygenation and water circulation, while also helping to remove carbon dioxide buildup. These stones emit a continuous stream of tiny bubbles that won't disrupt your aquatic life. Additionally, they promote the growth of beneficial bacteria and add visual appeal to your aquarium. They can even attract active schooling fish and strong swimmers who enjoy playing in the bubble currents. Designed to be used with an air pump, check valve, and airline tubing, Aqua One Air Stones come in a variety of sizes and styles to suit your needs.
