My pool was built in 1995 but this is my first year taking care of it. It had algea growing so on 5/6 I put 2 bags of pool shock in and chlorine tablets in both skimmers. The water is now clear and I have the following test results on 5/8: FC - 7.5 CC - 0 TA - 90 CH 440 CYA 100 PH 7.2. Two issues - CC = 0 and CH seems too high. What do I need to do?
