Do folks in Austin and surrounding areas actually close their pools? If not, I've read that I'm supposed to keep the pump running when temps get close to freezing.
Anything else I should know? Do we need to continue balancing pH and chlorine all winter long or is there some point at which we can stop running the pump daily and maybe just adjust chemistry at less frequent intervals? Do we still add PolyQuat at some point?
I saw the other day that a neighbor had let his pool go green. Is that ever a reasonable approach to the off season?
