I saw a neat little application called brewater 3.0. It allowed you to input your water values and then allowed you to adjust parameters to get the water where you want it. I was able to pick it up in an hour of playing if that tells you how easy it is to use.
If you want to play with it, you can download it at

I just got interested in how to adjust my water too. Figure ive played with the minor ingredients, why not the MAJOR ingredient.
