    ph keeps rising

    i like to keep my chlorine level at 6-7, i noticed the every time i add bleach to my pool my ph rises, is this normal? I then find myself battling with the ta, because when i add acid it lowers the ta as well.

    cya 50
    ta 80
    ch 300
    fc 5
    cc 0
    ph 7.2( added acid to lower it, was 7.7)

    Re: ph keeps rising

    Typically adding bleach will raise ph a little but when it is used up the ph goes back down to about where it started...we consider it ph neutral. There have been a very few reports of "cheap" bleach with excessive lye that can raise ph a little...but as I understand it, very uncommon. Do you have any aeration in your pool?

    Your fountain will raise the ph. Have you been using it recently?

    Re: ph keeps rising

    If you are going to keep using it, then I would let your TA go down a little more, but not below 60 ppm.
