Product Features

Fine bubble

Air stone refines the air output from the air pump into smaller and denser bubbles, achieving “atomization” effect. The size of the bubble can be adjusted with control valve, and the different oxygenation amount can satisfy different use requirements.

High-dissolving oxygen rate

Compared with ordinary air stone, the nano air stone’s surface is frosted, fine, and smooth. It can produce more bubbles and better agitate the water surface, thus dissolve more oxygen in the water.

Quality Nano material

The nano-stone is sintered at high temperature. The material is sturdy and durable with 2-3 years’ service life. It can be used for a long time and can help dissolve more air in the water. When the bubble bursts into the water, it barely makes any noise. T-type interface makes the air plate closer to the bottom of the fish tank, and the air is smooth.


The weight of the air stone is 15.2 oz / 430 g and can be easily placed at the bottom of the fish.

Please NOTE the deeper you put the air stone under water, the larger wattage air pump you may need to drive the air out.

Directions for User

1. If the dirt is blocked and the air bubbles are reduced, you can be take out the air stones and wash them repeatedly.
2. It is better to soak in the bathtub for two hours before use.
3. If the water depth exceeds 40 cm, the power can be increased as appropriate.
