Depending on the builder we go with, our build might be able to start relatively quickly, and even be plastered by early August. We have a week trip planned from Sept. 5th-12th and I'm concerned that might be too early in the startup process for the pool to be left unattended for a week. I've read keeping the PH in check is critical, but I don't know how you do that if you're not around to check it. Will the PH have settled down after almost a month? Is this enough of a concern to wait until after our trip to have the pool installed?
