Just wanted to say to Silver$, AJ and dozens of others on these mash pH threads, these have been tremendous in helping me figure out some problems with my beers. As advocates and curators of this stuff, its probably easy to get caught up in the tragedy of the commons, but I can assure you there are lots of visitors who have thoroughly enjoyed a nice day in the park.
At this point in my life, I am not going to spend 6 years studying chemistry. Leveraging people that have spent a lifetime doing it is a pretty good alternative. Thanks for the contributions. Big help.
