Was wondering if extremely cold water affects our test results for chlorine and ph. I do not cover my pool and my water looks a tad cloudy. My CYA is maybe 10. Chlorine DPD drop test is 6 ppm. Ph is 7.5. TA is 110. No combined chlorine was detected when tested. Another question comes up too, do I need to use more chlorine to achieve the same results that I get in 80 degree water?
