Water treatment, additional knowledge

Is there a resource out there that can help me understand water, how to read the Nashville water breakdown, and what each one means? I was at jack alone today and takes to Steve. He was brewing the rompo red and I asked him what he added to his water and he said it was simply calcium chloride. Jamil doesn't give a lot of info on water treatment, while John Palmer is all about some science and water treatment. Since water is super important I think it's time to understand it more. I've been brewing for 7 months and have 19 batches completed, and I think it's time to learn. I'm an all grain brewery, and I guess that matters more for us than extract, but since I don't brew with extract that debate doesn't matter. What info do you all have on this issue?

Doubtful that what your water company gives out will have all the necessary info needed to plug into a water program but if you post it up someone may chime in.

Myself and many other brewers have used these guys to get our numbers

Once you have your water makeup you can utilize these resources

This is from the top of the section you just posted in

And this is a spreadsheet/ program created by @mabrungard who has posts in that first HBT link

And here's a book you can buy on amazon that was written with the help of people from the first homebrewtalk link I posted
