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.
