    PH Bounce

    Here are my numbers

    FC 6.5
    CC 0
    PH 7.8
    TA 75
    CH 325
    CYA 75
    Salt 3300

    I try to keep the PH at 7.6, but it seems I have to keep adding MA to keep it down, is that normal, I have never let it go over 8.0....Thanks for a sparkling pool...

    That's very normal with a SWG. Try lowering pH to 7.4 and stretch the acid interval a little.

    As your TA comes down, the time between acid additions should get longer. Eventually the PH may be stable at 7.8.

    TA is at 75 I don't want to go much lower, or is that not a problem? Thanks Jason

    TA down to 60 is just fine. I wouldn't go below there unless you are also using borates.

    Re: PH Bounce

    I brought the PH down to 7.4, had to go away for 2 days, when I came back these were my numbers.

    FC 5 down from 6. PH 7.6 up from 7.4 CYA 60 down from 75

    I did add 6 vitamin c tablets on some stains to remove them, which they did.

    Should i adjust? Thanks

    I just tested my CYA with the pump running for 2 hours and its back to 75 where I wanted it...
