    winter PH level

    For whatever reason my PH has fallen to 6.9 over the past month ... that's a separate topic ... my question is, should I raise it up BEFORE I close my pool for the winter? Or is this something that can wait until next Spring/Summer to resolve?

    I'd raise it to about 7.2. It will naturally rise a little during the cold weather so you don't want to raise it too much, but you don't want it low for very long either.

    By far, the most common reason for that is using pucks for chlorination.
