I found it interesting, while reading over at the Taylor company's website, that the dropper method of testing is still the "gold standard" for water testing. In that light, I'm highly suspect of the chlorine readings I'm receiving from the one company that uses a test strip and a computer to evaluate my water. In the last water test I had done, the dropper-based pool company said my TA was 160, whereas the strip-based pool company said my TA was 100. Other numbers were all different, too, but not by much (stablizer is 70, 80; salt is 2700, 2900; calcium is 275, 300).

I found it interesting that in the Pool Tips link at PoolSolutions, they say that a simple OTO test kit is the best kit for everyday testing. I'm inferring, then, that the K-2600 is more accurate, but perhaps a little more tedious to perform - true, or no? I'll be anxious to get the K-2600 kit and compare its results to my OTO kit and the two pool companies I'm having test my water. I'm curious to see to which other test does the K-2600 most closely align.
