WHAT I DID
1. Drill 13/64 inch "vent" hole in the bottom of the bottle as shown. 2. Strip mesh bag(s) of anything other than mess, such as labels or string. 3. Loosely stuff mesh into bottle as shown. Evenly distribute inside bottle to avoid channels where large bubbles can form and run. 4. Drill a 9/16 inch hole into cap and expand with a piece of 1/2 inch CPVC tubing as shown. Place cap on bottle. 5. Place the TEE on one end of the 1 inch piece of CPVC tubing and the bubbler bottle on the other as shown.
