    PLEASE HELP!!! PH issue

    Hi All,

    It seems like I have to add Muratic Acid on a daily basis to keep my PH down at normal levels. I try to keep it between 7.2-7.8 I'm adding about 1/2 gallon every 2-3 days just to bring levels down to 7.5-7.8.

    This is a Salt pool and I never had a hard time last year like I'm having this year. BTW my pool water is around 82 degrees.

    Here are my current readings of what I've taken:

    TA - 90-100

    Chlorine 1.0-2.0ppm

    This is what I have for now. Hopefully it's enough to at least point me in the right direction.

    Read Lowering Total Alkalinity

    A SWG will tend to cause the pH to rise, but if you lower your TA, then the pH rise should not be as fast or could even stabilize. Your TA is above the Recommended Levels for a SWG system, so that is likely your problem.
