I'll keep it brief.
When I test my pool water using a 10ml water sample, after my FAS-DPD CL test, I check for CC and I always get a slight pink tinge.
When I use my normal 25ml sample, I never get a pink tinge when testing for CC. Even if I add 10 drops of the CC reagent instead of 5.
Suggestions, conclusions, advice, reasoning?
