Material needed: 1/4" air tube (green one), 3/4" PVC pipe and 3/4" socket. Make 1/4" hole on PVC pipe Cut 45d angle at the end of air tube Slot in the air tube to PVC, make sure its air tight
Test it first, you can adjust the air bubles by rotating the air tube or deepen it If you satisfy with the bubbles, put some aquarium glue around the joint to ensure there will be no air leak Connect the venturi to your existing pipe via socket ... and the venturi in action.
