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. 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. Air pump wattage: The weighs of air stone is 1.8ounces/51grams and is easily placed at the bottom of the fish tank, suitable for fresh water and salt water.
