Attention:

1.As this atmospheric dual hole aquarium oxygenator fish tank starter produces mechanical movement when working, it will not be 100% silent, if you think it is not silent enough, we recommend you to pad a towel or thin cotton underneath this oxygen pump before using it I believe it will have better effect.

2.When you need to place the oxygenator pump in a position lower than the top of the fish tank needs to be ventilated hose needs to be connected to the non-return valve (package included) to use, to avoid the backflow of water from the fish tank, damage to the oxygenator.

3. When placing the oxygenator in a position higher than the top of the tank, there is no need to connect the non-return valve.

4.When the air pump is below the water level, install a check valve as indicated by the check valve (“out” is the direction of the air outlet). We provide 2 air stones for you to replace and connect to the tubing for more oxygen.

5.To prolong the life of your aquarium air pump, we recommend you to clean the silicone tube and air stone regularly.
