I am a bit confused. With the TF100 kit you get the combined unit that measures TC and pH together at the same time. Then you can also do the drop test to obtain FC and subsequently CC. My understanding is that TC - CC= FC.
So why do I need to know my TC from the initial TC/pH test? Why does TC really even matter, if the drop test gives me FC and CC results? After all TC really doesn't matter with respect to the other two does it? I could see if you didn't have the drop test for CC you would need it but don't understand the point in the TC test with the TF100.
