I am about to invest in my test kit. I know you suggest one of two types: the TF Test Kit for about $100 (including shipping). Then there's the Taylor K-2006C. The Taylor is more expensive (like $140 best price on Amazon). Oddly, it seems that in your comparison of the two, the Taylor (though more expensive) doesn't seem to have your basic Chlorine OTO test. So, how would you test chlorine levels? Am I reading this wrong? I'm considering the Taylor because there is a deal on an unopened kit but, in addition to wondering if the deal is on a legitimate test, I'm wondering if there is really no OTO test.
