Another short one for you today, This quick little video is to show you what the One Way Valve looks like. The one way valve connects to the biorb air pump to prevent water from leaking back into the air pump. If the air pump is kept below the aquarium and the one way valve fails water can leak into the biorb air pump causing it to malfunction.
This video shows the Reef One biOrb/biUbe One Way Valve in the bag. The valve provides extra insurance in the unlikely event of water leaking into your air line, or for extending your air line.
At least every 6 months a check should be made by disconnecting the air pump and lowering the air line below the water line. If you wish to extend the length of the air line from your aquarium it is advisable to do so with a one way valve.
