I have heard, and it makes sense, that in order to keep those aeration stones clean you need to turn on the O2 before you put it into the wort, that way the pressure keeps the wort from working into the pores. If it gets in there and gets caked up you might have it pop off as one poster states, or infections, or just plain clogged. I just got mine, I have not used it so I am just passing along what I heard.

That's correct. I boil mine for a few minutes then it sits in starsan. I turn on the gas and once I see bubbles I put it in the worth, aerate, then back in a bit of water and then starsan for a few seconds before I kill the gas. Sounds like a lot of wasted o2 but I'm on my 10th batch OJ same tank.

Every scientific research report ive read has said pure O2 is the only way to get over 8ppm. Optimal o2 level is 10-12ppm. You can shake and get 8ppm so if you aren't going with pure o2 it is just an effort to save shaking, which in itself is a good reason to get a wine degasser.

Very true.

I would guess that the reason people say they get just as good of results is the oxygen is needed early on for reproduction.
Depending on the OG of the wort and the amount of yeast pitched, the importance of optimal reproduction can vary.

Certainly. I went to pure O2 because the majority of what I brew is over 1.070.

I like to brew big beers also.
I've got a virgin O2 system that I hope to break in this weekend.

Personally, I seldom measure my beer...I drink it. My results using the MixStir are every bit as good as friends who use O2. What else matters?

Same here. Again, if the MixStir didn't give me excellent results, I would have switched to something else several hundred batches back.

when you say MixStir is it one of those paint mixers that attach to a drill? When do you oxygenate with it...in the kettle, or the bucket?

Yeah, pretty much like that. I use it once the wort is in the fermenter, but you could also use it in the kettle once it's cooled.
