    Vacation for a week, what to do about PH?

    I have a fairly new plaster pool (January) and am still fighting almost daily PH creep, it'll go from 7.6 to 8.2 in a few days if I don't keep an eye on it. We are going on vacation for about a week soon and I was wondering what to do about that? I read a lot of threads that talk about chlorine but I wasn't able to find anything regarding PH, it seems for chlorine the advice is to bring it to shock levels and add a tab or two in a floater and let it fall while i'm gone. Using the same logic should I add acid till i'm at say 7.0 or lower and let it rise or should I do nothing and deal with the high PH when I get back? Having someone come by isn't likely to be an option, or else I would do that.

    You could take your pH to the low end (7.2-ish) knowing it will rise fairly quickly anyways. I wouldn't go any lower though. You could also add a couple tri-chlor tabs to a floater which are acidic in nature and should also help to keep pH down a little. Of course tabs increase CYA too, so be aware of that. The Poolmath Calculator (link below) has a row at the bottom (Side Effects of Adding Chemicals) that can give you an idea of what to expect by using them. Hope that helps.

    What is your CYA at now, if you can handle adding CYA for the week I think it may help keep your PH in the lower scale...

    It's currently at 50, so not too bad. We get a LOT of sun here too, so adding a bit more probably isn't going to be too bad.

    You should be good then. That CYA will come-in handy real soon.
