I'm interesting in aerating my wort with oxygen but I am unsure which route to go. I know the disposable BernzOmatic tanks are the most popular but I'm concered with the low quality of some of the regulators made for these disposable tanks. Some of the threads I've been reading complain of leaks and other issues with these regulators. I would rather spend a bit more money upfront and not have to get a new $12 disposable oxygen tank every 2 or 3 brew days. As a result, I have been looking into welding oxygen tanks with heavy duty regulators. I'm interested in other peoples setup and how you connect your sintered stones to these welding tanks.
