    Ph high after shocking

    Today my pool was starting to get cloudy. We have had quite a bit of rain the last few days. Also, a couple days ago i had decided to supliment my liquid bleach clorination by turning on the clorinator. i have a bucket of pucks and thought i could slowly use some of it up. Not sure it had anything to do with the cloudy water but thought i should tell you i used it again for a couple days.

    Tested water :
    FC 2
    CC .5
    TA 140 (not sure I'm getting accurate results- 2 pool places tested 2 days previous and were in the 80's)
    Ph 7.4
    CYA 30

    Decided to shock. Added 738 onces of 6% bleach. That was what the pool calculator said. FC went past my 15 ppm goal to about 22 ppm. Ph went to 8.2. I know the FC will come down how about the PH? Should I just watch it for a couple days and it will come down or do I have to add acid. I stopped using my chlorinator again. I started to use 6% bleach to chlorinate after I found this site. Waiting to see if shocking will improve the clarity of the water.

    With FC above 10ppm, pH test becomes invalid....disregard it

    Holding your FC high and running your filter should help clear it up. And as Dave said, don't worry about your pH until your FC is back below 10 ppm.
