Mostly curious about FC testing with the TF-100. I understand the extended test results for getting testing down to .2 ppm, but is it possible or wise to save on regent and test for higher levels? Such as using 5 ml of water...would that make each drop of regent value be 1ppm?
And....can you test for CC WITHOUT testing for FC first?
Haven't seen this covered and wanted to get a "professional" opinion!
