Bekka,

Nope. TC is total chlorine. FC is Free Chlorine. CC is Combined Chloramines.

CC's are a very ineffective form of Chlorine...doing little good.

If you have an OTO test kit, your results are TC...the total of FC and CC's

If you have an FAS-DPD test kit, you test for FC and it gives you the ability to test for CC's as well.

Hard and Fast rule: FC + CC = TC

(When you "shock" a pool (also called breakpoint) it burns off the CC's leaving you with only FC...a very good thing. )
