Thanks so much for your help! The pool is finally looking mostly great. The pool is like 95% clear, which is a huge improvement. I can clearly see the bottom in the deep end even with swimmers in it. I am adding chlorine 2-3 times a day to keep up with the chlorine demand.

TA 100
FC 2.8 (this morning it was 4.4)
CC .6
CYA 0 I added more 2 days ago, but have not tested since. The chemical may be expired since this is the second time I have added it this year and it has dropped
pH 7.3
CAL 280

I am using the chlorine tablets left over from the Pool Frog. Those will be gone in a couple of weeks. I have the chlorinator set to "3".


How do I shock to eliminate the CC when I am trying to keep the copper dissolved in the water?
