Atmospheric emissions of harmful gases in water- By noxious gases from the decay of carbon gas and residual feed and fish feces discharged from the breathing air bubbles rise to discharge into the atmosphere. Expansion of water surface area- Be widened to blue caused by fluctuations of the water surface area of rising air bubbles and injuries by increasing the contact surface helps the air and the water supply of oxygen in the atmosphere. Convection of water in the tank- Injury bubbles and moving water that rise to a uniform temperature in the tank. Lively and refreshing- It gives a visually vibrant cool refreshing move.
