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 airstone, 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.
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.
The weight of the aquarium airstone is 15.2 oz / 430 g and can be easily placed at the bottom of the fish tank.
Please NOTE the deeper you put the fish tank air bubbler underwater, the larger the 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 take out the air stones and airline tubing, 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.
