After reading the info on the Wyeast website about aeration (Wyeast Laboratories : Home Enthusiasts : Brewers : Technical Information : Oxygenation), I got to thinking about how to better use the aquarium pump I have to try to hit the equivalent of 10ppm dissolved O2 that is supposedly ideal.
My idea was to keep the aquarium pump (using sanitary filter and stone) running during the first few hours of fermentation, so that as O2 is consumed by the yeast it is replaced constantly. I know I can't be very precise with this method, but I hear it is pretty hard to overdo it with air as opposed to pure O2.
The motivation is to try to improve attenuation on higher gravity beers. I will be doing a few things differently next time, and this is the only one of which I'm unsure of the benefit, if any.
I'm not opposed to using pure O2, but it's just one more thing that I'd rather not plunk down cash for.
Any opinions or advice would be welcome.
Thanks
