Connect the other end of the hose to the non-return valve. Continue connecting from the non-return valve to the diffuser (air outlet). Place the diffuser in the aquarium and adjust the air volume at the outlet. Note: The air hose can be connected directly to the diffuser without a non-return valve. However, non-return valves are recommended to prevent backflow.Zoo-Roco tipIf possible, place the air pump above the water level or use a non-return valve in the air hose. This will prevent water from running back in the event of a power cut. A soft base (e.g. sponge rubber) often helps to ensure quiet operation so that vibrations are not transferred to the furniture.
