Where is the oxygen switch in the fish tank?

If the backflow prevention valve is installed, the oxygen pump can be placed at will; If gas stone is placed, the oxygen pump should be placed above the water surface of the fish tank. To install the backflow preventer, it needs to be installed in the middle of the pipeline connecting the gas stone and the oxygen pump. Connect the socket on the oxygen pump to a pipe, and find an air stone at the other end of the pipe; Throw the gas stone into the fish tank. Then turn on the oxygen pump, there will be bubbles coming out, but the height of the oxygen pump is higher than the water surface of the fish tank.

Note: oxygen pump has two main parameters, one is power and the other is gas volume. Generally speaking, two parameters are related, high power and high gas volume. The greater the air volume, the deeper the fish tank can be used. When the water is shallow, the air pump with large air volume will splash, and the fish tank with deep water will use the air pump with small air volume, and the bubbles will be smaller or even no air will be released. Similarly, the louder the volume, the louder the vibration, and the quieter the volume.

The air pump with adjustable air volume is preferred. Generally speaking, the air volume of these air pumps will be above 1.5L/min, but it can be adjusted by manual knob. Generally speaking, the gas volume adjustment knob of imported oxygen pump is reliable, while some domestic brands of oxygen pump gas volume knobs are not sensitive.

If the water level in the fish tank is below 20cm, choose an oxygen pump with fixed air volume 1- 1.5L/min, and add air volume control valve to adjust.
