I recently got one of those pure O2 aeration systems and a disposable benzomatic tank. I want to know how long I should run it for. I have read many of the posts about this and have found times between 30 sec w very little flow, to a few minutes at full blast. So I figured I would be safe doing about 45sec, until the product showed up with directions that say to pump for 15-30 MINUTES. I just want someone who has done it a lot to tell me how long they do it. I assume the OG also is a factor. Like I said, I only did it for about 45sec last night, and then pitched a full yeast cake (O.G. was about 1.085). Am I good, should I do it some more?....
