About 1 week ago pool was green. I have been running pump 24/7 ever since. I have also kept my chlorine level between 20 - 25 during that time. As of now the pool is blue, but cloudy. The part that is troubling is that all of last year my CYA level was around 80 - 90. Now it is a lot lower this year. I realize that it will drop some due to backwashing and re-filling, but according to the black dot test I am guessing CYA levels are around 40 - 50. But when I took a water sample in today to my local pool supply store they told me it was at 12.
Should I be concerned? Would the high chlorine levels cause my test and their test to be off? What should I do. I was about ready to let my chlorine levels come back down since all the green is gone, but I am not sure now.
Current readings:
FC: 22
CC: 0
PH: 7.4
Alk: 111
CYA: Not sure?? I guess somewhere between 12 and 50.
