🐟Nano air stone plate refines the air output from the air pump into a particle bubble, which is smaller and denser, like the "atomization" effect, and the bubble size can be adjusted, and the different oxygenation amount can satisfy different use requirements

🐟High dissolved oxygen rate:Compared with ordinary bubble stone, the nano bubble stone emits more bubbles, and the gas and the water surface are more widely contacted, which makes the dissolved oxygen amount larger

🐟Quality Nanomaterials:The nano-stone is sintered at high temperature. It has good permeability, sturdiness and durability, long service life, and will not break. It has excellent performance in oxygenating water, which can ensure the health of your pet fish, shrimp and aquatic organisms. When the bubble burst into the water, the sound is super quiet.Suitable for use in fresh water or salt water.

🐟Air pump wattage:The weighs of 4 inch air stone is 15.2oz/430g and is easily placed at the bottom of the fish tank, suitable for fresh water and salt water. It is driven by an air pump of 4 watts or more. PS: The deeper the water, you may need to use a larger wattage air pump to drive it

🐟Suitable fish tank size
2 inch Suitable for fish tanks about 40-80cm
4 inch Suitable for fish tanks about 90-180cm
8 inch Suitable for fish tanks about 180-300cm

🐟Steps of installation:
1. Immerse the air stone in water for 2 hours before using it for the first time.
2. Connect the air stone to the tubing and the tubing to the air pump next.
🐟Package Included:
1 x 2inch/4 inch/8inch nano air disk stone
1 x control valve, 
1 x check valve, 
1 x suction cup, 
1 x Y-shaped connector, 
1 x 3M Hose (Note: Air pump are not included)
Tips:
1. Immerse the air stone in water for about two hours before first time using.
2. Please properly increase the wattage of pump if the depth of the water exceed 90cm.

3.It is recommended to clean the algae and other impurities on the surface of the disc regularly to prevent blockage of the stone disc.
