This 8-inch Air Stone Bar (Model AWB-200) delivers strong aeration for aquariums, DWC buckets, hydroponics setups and fish tanks. It produces two bubble effects—fine bubbles with low airflow or medium bubbles with stronger airflow—creating a rectangular bubble wall that boosts oxygen levels and water circulation.

Made from high-quality grey mineral sand with a durable plastic base, this air stone is safe for all aquatic environments and stays securely in place thanks to the included suction-cup clip.

Perfect for any standard 3/16" airline tubing and recommended for air pumps above 4W.
