The TF test kit site referred me to your forum to answer the following question:
I am using the TF-100 test kit with a bromine pool and need to
know how to convert the FC and CC test results to bromine. The FC is
at 16.5 and the CC is 1.5. Thanks for your assistance.
I know that you multiply the FC reading by 2.25 to get the bromine level. The CC is a different story, one of the experts will have to answer and I am not sure how CC even applies to bromine water chemistry.
You don't measure the CC and it's not relevant anyway. Bromamine is a reasonable sanitizer and it apparently registers in the FC test along with bromine. Just for the heck of it, you could try adding the 5 drops of R-0003 to see if you ever get any pink.
