Airstone Disc Air Stone for Aquarium, Round, Boosts O2 Levels, Improves Water Circulation

DescriptionThe KW Airstone Disc is an essential addition to any aquarium, designed to boost oxygen levels and improve water circulation for a healthier aquatic environment. This ISO9001 registered air stone features a round disc design with a distinctive orange rim, and works by diffusing air from your pump into a steady stream of fine, beautiful bubbles that rise through the water. Simply connect the L joint to the air disc, attach your tubing, and place it in the tank — allow it to soak for 15 minutes before switching on the air supply. The volume and pressure of your air pump will determine the bubble coverage area. Over time, algae may build up and reduce airflow, so remove the disc and clean it with a stiff brush to maintain performance. If the L joint is not used, embed half the disc in the sand to prevent it from floating up. Ideal for fish tanks of all sizes, this air stone aerates, decorates, and keeps water circulating efficiently, creating a vibrant and visually appealing aquarium.
