I have been using the TF-100 test kit for everything except the pH and a Chem-Tek 5 way test kit for the pH (because it has the ability to adjust for high chlorine levels). However, this year I am nervous about the discrepancy noted on the pH between the test strips (getting a 7.2) and my Chem-Tek 5 way. (getting a 7.8). My gut says to trust the Chem-Tek drops, but I don't understand why the test strips are reading so low.
