Tips to better use the air stone:

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-inch depth.
3. Clean the algae sand and other impurities on the surface of the stone 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 regulated, the more delicate the bubble will be.
