Quiet and stay in the tank. Durable and quiet aquarium air stone with fine bubbles.

Key Features:

• Fine air bubble: Aquarium air stone refines the air output from the air pump into smaller and denser bubbles, achieving an “atomization” effect. The size of the bubble can be adjusted with a control valve, and the different oxygenation amounts can satisfy different aquarium requirements.
• High-dissolving oxygen rate: Compared with an ordinary air stone, the nano air stone’s surface is frosted, fine, and smooth. It can create more bubbles and better agitate the water surface, thus dissolving more oxygen in the water.
• Quality Nanomaterial: The nano stone is sintered at high temperatures. The material is sturdy and durable with 2–3 years of service life. It can be used for a long time and can help dissolve more air in the water. When the bubble bursts to enter the water, it barely makes any noise. The T-type interface makes the air plate closer to the bottom of the fish tank, and the air is smooth.
• Lightweight: The weight of the aquarium air stone is 15.2 oz / 430 g and can be easily placed at the bottom of the fish tank.
