Thanks for posting the link. I signed up too and looking forward to it!
Jim, I'm with ya as I'm starting to jump into water chemistry too! I'm reading Palmer's new Water book and got a little overwhelmed. It's like being back in class, as I started taking notes while reading the book and browsing websites such as Martin's Bru'n Water and his Water Knowledge page.
The key for me, was understanding the RA. From there, everything else started to fall into place for me and things started to make a little more sense to me. I'm sure once I get my water report, I'll be posting it and asking a truck load of questions.
