Thanks, Larry. They are a little pricey, but this might be a great way to go. I just hope the digital reader has better eyesight than I do.

Thanks CG, that helps a ton. It's certainly no worse than the test strips I've been using, which is good enough for me to give it a try.

I suffer from mild red-green color blindness - I have a hard time distinguishing small differences on some pads on water test strips, although I think I can see things well enough to keep my water in mostly decent shape. I want to upgrade to a real water test kit, but before I fork over the bucks, I thought I'd ask if color blindness will make reading the results harder than reading test strips. Brightness helps me. Are there kits where the color matching is brighter than others? Or are there techniques that make it easier to distinguish subtle color differences? I think color blindness is fairly common - are there folks here who test their water with less-than-perfect vision? Thanks in advance!
