    Acic, acid and more acid!

    Please tell me if this is normal.....

    Pool re-plastered two months ago and since then I must have added at least 8 gallons of MA to keep pH in check....trying to get it down to 7.2 so I can get the TA down too.....
    Seems like lots of MA, just looking for reassurance that using this much is normal with new plaster.
    I have been adding a quart at a time, wondering if I should give it a bigger blast?

    FC 3.5
    CC 0
    pH 7.7
    TA 100
    CH 260
    CYA 50
    Borate 80

    That is all normal. Fresh plaster raises the PH rapidly for the first three or four weeks, and then much more slowly for about the first year.

    On how much acid to add at at one time, your goal should be to lower the PH to 7.2 each time you add acid, however much muriatic acid that takes. You can use the Pool Calculator to get the approximate amount of acid that will take, and then you should double check by measuring the PH about 1/2 an hour after adding acid to see how close to 7.2 you got and adjusting how much you use the next time based on how far off you were.

    I know how you feel Sometimes there seems like no end to adding MA! We re-plastered in '07.

    MA, brush, MA, brush, MA, brush, MA, brush ..........

    But, as they said, it will slow down and you will be hunky-dory with your new plaster

    The borates will cause you to use a lot of acid, but the pool calculator takes that into account, so you should be fine.

    See, that's what this site is all about. The FIRST priority is keeping pools Trouble Free -- the second is to share the entire 'experience of pools/ yard/ BBQ"' and still be able to interact with folks who share similar interests, not pool related

    My first show was 03/ 26 (?)/ 85 - but I'd been listening to my brother's bootleg tapes for years before
