I have bought the TF-100 kit and used it a few times but still confused. What I am confused about is the kit comes with a Basic K-1000 which has a "Cl" test. So the "Cl" test is not the same measurement as the TC from the larger kit (TF-100)? The word on the k-1000 instructions says "Total Chlorine Test" is making me confused.
FC = free chlorine
CC = combine chlorine
