I have an online O2 setup I built. The stone is a 2 micron. From what I've read and seen online the times vary. Some say 30-60 seconds, other say I.E. 5 gallon batch run 2.5 gallons in before turning it on for the rest. What would everyone suggest? I've used it once, and did the 2.5 no O2 then turned it on for the rest. The picture doesn't have the stone in it, but it is currently screwed into the bottom of the T.
