water looks great! much clearer, that murky color is gone! pool was holding at 20 tonight! i have a question, when i check for cc it is colorless but, today i got side tracked for a few minutes and when i looked at the test cell it was slightly pink added 1 drop went clear, waited a few more minites and it was slightly pink again added another drop was clear. I did this about 5 times then i just quit. is this normal? do i have cc? Shoud you always let it sit or not? Thanks in advance.
