The TFTestkit 100 uses the same Taylor reagents as the K-2006 for the most part. It does not include 2 tests that are in the K-2006 (acid and base demand, which are not really needed) but does included a wider range pH test and a daily OTO chlorine test (both Taylor) and included a wider range CYA test (also Taylor) It also includes more of certain reagents that are used up quickly as compared to the amounts provided in the K-2006. All in all I would have to say the TFTestkit 100 is a better bang for your buck!
