First time posting. Great forum!
We started using our Taylor 2006 test kit recently and we've noticed several times that with the free chlorine test, when we add another drop (after having added a few), the pink color will disappear in the tube after swirling, but then 15-30 seconds later we notice that a slight pink color reappears. We wondered whether we should ignore the reappearance of pink and move on to the combined chlorine test or go with that and keep adding more drops until the pink doesn't reappear 15-30 second later? Thanks!
