pH tested, no adjustments necessary?

[ScrewyBrewer]

.....Bru'n Water presents a bunch of water profiles that include researched regional profiles, color and perception-based profiles, and style-based profiles. While I'm for simplicity, some brewers do want the ability to think for themselves.

Regional water profiles will provide insight into the water properties of a region. But knowing how to treat those waters for use in brewing is the challenge. That insight is something to learn on brewday mostly by trial and error.
