    Going away for week- ph question

    Hi all-
    FC 5 pH 7.5 TA 80 CH 475 CYA 80

    New plaster pool still 'curing'. Have to add 3 cups muriatic acid every 2-3 days to keep pH between 7.5 and 7.8
    Going away for week. Don't feel comfortable asking neighbor to handle acid for me.
    DO I over compensate and bring Ph low and have it float back up to normal over the week, or do I let pH go high and push it back down when I get home?
    In other words what's worse, a low pH or a high pH?
    I know acidic water no good for pipes ad equipment but worried about scaling with a high pH and a CH of 475.
    Not worried about chlorine- I have a SWG.
    Thanks all in advance!

    Take it to 7.2 just before you leave, and it will be fine. And it doesn't sound like you have much choice anyway. If it were me, that's what I would do in your shoes. Pipes are PVC, so no worries there at all.
