Default oxygenation foam!!

I just started full boils, and subsequently am using a pure oxygen system with a diffusion stone. My problem is even at a low setting the oxygen foams the wort so greatly I can't oxygenate for over a couple minutes without it trying to foam over. Would an anti foaming agent work or any other suggestions would be appreciated

Don't use any anti-foam agent. That stuff doesn't have any place in brewing.

With pure O2, you only need to oxygenate for 1 to 2 minutes anyway. What kind of diffusion stone are you using? Is it one of those stainless steel ones?

Set it on low, as soon as the foam hits the carboy neck, you're done. 2-3 minutes is plenty.

How long can you keep it in the secondary once you dry hop it?

My aeration system from Williams brewing says only a minute and your good. I used it yesterday and at 1 minute there was foam to the top of the carboy, so it worked well. I have a nice fermentation going on 10 hours later.

I also use the wand from William's, 90 seconds is sufficient for me. The stone that they use is a 2 micron stone.
