cloudy water

I added another gallon of bleach before bed. This mornings readings were:
FC 23.5
CC 0
PH >8
Is the off the charts pH due to the high chlorine? And is it really that high right now, or is it a false high? Do I need to worry about the ph then while I'm shocking if it's a false reading? Based on the chlorine chart, my shock level should be above 20. Since this morning it is only slightly above 20, should I add another gallon to carry it through the day and then take a reading tonight/tomorrow morning to see if everything is ok? If I add the gallon this morning, will it be circulated enough to do the test this evening/tomorrow morning or will it still be rising during the night? Thank you for your help.

Sorry you didn't get a reply til this evening. I assume you tested this evening. Test again in the morning and see how much chlorine you lost overnight. You are right that the pH reading will be falsely high when your chlorine is high.

Late afternoon I tested it and it dropped below 20, so I added 4 gallons of 12% bleach in the hopes that will raise it enough to get through the day above 20 so then I can test it tomorrow night and the next morning and know that it is still above shock level. I wasn't sure how long from when I add the chlorine that it would register when tested. Maybe it would be ok to test tonight after all? I was more concerned with keeping it above shock level with this hot weather we are having for a few days. Is that right thinking? I figured it couldn't hurt to keep it up for one more day?

With your volume, I would say that you need to give it about 3 or 4 hours to mix in well before you get a reliable reading.
