Product Name: Complete sand table. Material: silicon carbide. Product specifications: The tracheal articulation measures 4 / 8mm Product characteristics: The high temperature sintered air stone is made of high temperature sintering, which is different from the general commercial air stone. The material is robust and durable. It can be washed repeatedly and used for a long time. Uniform and fine bubble bubbles it is not easy to block bubbles, more gas and water wide exposure and high content in Dissolved oxygen Adjustable size Adjust the output area of the bubble as a function of the power of the oxygen pump, the lower the air volume < p> less there are bubbles produced
