Plan to be away for a couple weeks and want to know if the pool can handle the rising pH. I am not worried about the chlorine because that is supplied by an SWG, but the SWG does cause the pH to rise. Generally I add 12 to 14 ounces of muriatic acid every two to three days to keep the pH in range. For vacation I was figuring on dropping the pH to 7.2, which should give me 5 to 7 days of pH below 8, if I'm lucky. Will my plaster pool be ok if the pH rises above that for about a week? Thanks.
