Aqua One Check Valve Installation
- Measure the airline to the length required.
- Cut the airline so that one length will reach comfortably from the location of the air stone to 10-20cm outside of the tank.
- The check valve is a one way valve. To establish which way to place the valve, look for the arrow shape inside. The arrow should point to the aquarium. If you don’t see an arrow in the valve, you can check which way the valve works by blowing through it. The end you can blow through should point toward the pump.
