♦♦ How to Use RS-628A Transparent Aquarium Oxygenation Pump

1. Connect the oxygenation pump, the hose and the bubble stone (sand head) properly.

2. Ensure that the aeration pump is placed above the horizontal line inside the fish tank, or add a stop valve in the middle of the hose to prevent water from flowing back into the aeration pump in case of power failure and damaging it.

3. To extend the service life of the air pump, please replace the bubble stone regularly.

4. The oxygenation pump must not be submerged in water. If it accidentally falls into the water, please immediately cut off the power supply and then remove the air pump.
