I'm using a 5lb bottle and a regulator that I purchased from the local home
brew supply. For a needle valve, I am using a brass aquarium airline
valve. I removed the rubber "boot" inside the valve and screwed it finger
tight(snug). I adjust the pressure to get the amount of flow I need. The
brass valve acts as a controlled "leak". It takes about 5 to 7 lbs of
pressure to get one bubble per second. I've been using it for eight months
with no problems. The pH holds constant at 7 and my last cylinder refil is
starting on its 7th month.
