Bru'n water software would be a total waste for me. My water changes often. I'd be willing to bet all ya'lls water changes regularly as well if it is coming from a municipal source. You can type your report into any field you want but that doesn;t guarantee that your water is anything like that report on any given day.
On light beer or dark beers I have to make adjustments (amber beers almost always hit spot on) and I personally wouldn't trust anything but a meter. I keep the strips around "just in case" but I don;t really trust them either. I never have been able to find the exact color match, even on the colorpHast strips.
