I am going on vacation soon and I am concerned on what to do with my pool while I am gone. The pool is a new start up and I should be fine with everything except pH. The pool is new, 5/5, and the pH rises daily. I have a 13,500 gallon gunite and I add anywhere from 12-24 oz a day. What can I do while I am away?? I'd rather not have neighbors come over, but there are pool owners in next door and two doors down. Isn't there something that will leach out slowly a pH down so the pH will be maintained while I am gone??
