Default O2 regulator - how to use it

I bought all the necessary shyt to oxygenate my wort. My question is how "open" do I leave the regulator to oxygenate? Wide open? Quarter turn? I don't want to over or under oxygenate. Thanks in advance!

Here it is for reference: http://www.homebrewing.org/Oxynator-...it_p_1057.html

I have the williams brewing wand with the stone attached, I open it until I start seeing bubbles coming to the top, this is far from wide open. I let it run for one minute

It doesn't take much to get these wide open. I always open mine up all the way and run it for about a minute.

Right on. There are suggestions (on par with what you said) on the website but figured I'd ask those that actually use it. Thanks homie.

yup.. and from my understanding (not to cause debate), you can't over oxygenate wort. You'll just waste the oxygen is all. Anything that isn't used by yeast gets forced out by Co2.

I used to use a stone in the fermenter for about a minute or two kinda swirling it around. Now I have an inline oxygenation system that is connected to the wort out of my plate chiller. I turn it on for half the batch then turn it off. It works amazingly well. It's crazy too when the wort runs with oxygen it turns almost white in the tube.

Kind of wish I went with that one, like the idea if the SS wand. I gotta figure out how to weigh down the tubing I'm gonna use.

get a SS racking cane. Connect the stone to the SS wand with a small bit of tube and some hose clamps.

I was just reading a study done regarding oxygenation of wort so this thread caught my eye. According to the guy who wrote this piece you can, in fact, get o2 levels to the point it becomes toxic to the yeast. Here's a link to that study:

I don't have any personal knowledge of the guy(s) who did this study. But it seemed pretty credible to me. You can read it and judge for yourself what you think.
