Aqua One Air Stones enhance your aquarium by providing ample oxygenation and water movement while aiding in the release of carbon dioxide build-up. They emit a continuous stream of fine bubbles, ensuring a gentle environment for your aquatic inhabitants. These stones also promote healthy bacteria growth and add an attractive visual element to your aquarium display. Additionally, they can attract active schooling fish and strong swimmers who enjoy interacting with small bubble currents. Designed for use with an air pump, check valve, and airline tubing, Aqua One Air Stones come in various sizes and styles, suitable for both coldwater and tropical setups.
