I have been trying to use my blichman quick carb to do double duty as an inline O2. First attempt worked pretty good but I ran out of O2. Think I went a little heavy on the flow rate for my 10 gal batch. My question is how long does the oxygen stay dissolved? In this example I oxygenated on the way to my conical. Once at the conical I like to let it rest for 10 to 20 minutes to then dump out the trub at the bottom. Am I losing DO in the meantime? and if so it is at a high enough rate that I should wait until I dump the trub to oxygenate?
