Easy to Clean: Please soak me in the water, gently brush the dirt on the surface with a brush, dry in the sun for half a day, and you will get a new perfect mano bubble stone. 
 
Range of Use: Office, fish tank, decoration, hydroponic environment. Freshwater and saltwater can do. 
 
Healthy and beautiful environment: The air volume of this nano aquarium bubbler can be adjusted by the control valve. 
 
High Dissolved Oxygen Rate: Compared with ordinary bubble stone, the nanobubble stone emits more bubbles, and the gas and the water surface are more widely contacted, which makes the dissolved oxygen amount larger.

If only a small amount of air bubbles are generated after the correct installation is completed, please turn off the air pump and then turn on the air pump.

We suggest cleaning the disc once a month.
