Main highlights

Quality Nanomaterials: The nano-stone is sintered at high temperature. The material is sturdy and durable. It can be used for a long time and has better dissolved oxygen effect. When the bubble burst into the water, the sound is super quiet

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

Fine bubble: Oxygen stone 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
