New to TFP and after recieving my test kit (TFP 100) I am unable to get the CC reading to work. I follow the below instruction and the solution doesnt turn back to clear. The last test went to 50 drops and the solution seamed to turn a deaper shade pink if anything. Am I missing something? Faulty reagent?
5. To test for Combined Chloramines, add 5 drops of R-0003 to the solution and swirl. If it remains clear, you have no CC’s. If it returns back to pink, add R-0871 as before, counting and swirling between each drop. Once the solution returns clear, multiply the added drops times .5 again…..this will be your CC reading. Record it. The total of FC and CC should be recorded as TC (total chlorine)
