The AWB-200 8-Inch Aquarium Air Stone Bar creates a strong, consistent bubble wall to improve oxygenation in fish tanks, DWC systems and aquariums. Designed for 3/16" standard airline tubing, it produces either fine bubbles with low airflow or medium bubbles with stronger input—ideal for boosting dissolved oxygen levels and supporting healthier fish and plant roots.

Built from compressed sand with a durable plastic base, this air stone is safe for all aquatic environments and stays stable thanks to its included suction cup clip. Perfect for freshwater, saltwater and hydroponic setups.
