I'd like to improve my fermentations by changing the way I aerate my wort (normally I just shake the carboy), and I've been looking at pure O2 equipment.
What I'm looking for here is advice from those who have gone through this process so I don't wind up wasting too much $$$. I do want to get "good" equipment for this, nothing cheap that'll fall apart or give inaccurate readings, as I'd like to be able to control the process so I can accurately track changes.
To this end; I've been looking at a 20 CF O2 tank (welding grade, new) and medical-grade regulators and flow meters. Seems a set-up like this is running around $250-300. I don't mind spending the money, but I'd like to do it once and be done with it.
Anyone gone through this before, and what did you wind up with? Do you use medical-grade regulators and flow meters, or industrial-grade regulators?
