Key Features Air stone kit accessories The air stone kit includes a 2-inch nano air disc stone, 1 control valve, 1 check valve, and 2 suction cups. Please note that the air tube and air pump are not included. Ultra-high dissolved oxygen The upgraded hygger fish tank air stone releases smaller & denser bubbles, doubling the oxygen dissolving rate in water. Produces tiny & dense bubbles quietly When the bubbler bursts into the water, it is less noisy. It can create the atomization effect, and bubble beams make your aquarium like a fairyland. Weighs enough to sink 5.2 oz/150 g, making the air stone easily sit on the tank bottom without a suction cup. The diameter of the air diffuser area is 2 inches, not including the plastic border. It is suitable for freshwater and saltwater. Driven by a 2W or larger air pump The 2-inch air stone is compatible with a 4 mm airline tube. Its output airflow is 1L/Min. Please note that the deeper you put the air stone underwater, the larger the wattage air pump you may need to drive the air out. Usage Tips 1. Please immerse the air disk stone in the water for 2 hours before use. 2. Please increase the wattage of the air pump properly if the tank water exceeds 15 inches in depth. 3. Clean the algae, sand, and other impurities on the stone’s surface once a month, or when you find a decrease in air output. 4. When the power of the air pump meets the bubble stone, the smaller the air output is, the more delicate the bubble will be.
