I intend to keep the pool open at least 15 weeks! It just might not be as pleasent as Florida, haha!Your 'extra chemicals' will be a joke by comparison if you go larger and it will only matter for 8 weeks of Buffalo summer. It's already hotter in FL than you'll get in August.
It was very difficult for me to pull the trigger on the pool. I am quite frugal and it's not lost on me that Buffalo winters are short. The costs of this pool are far lower than a full fledged membership to a very nice country club. Yet here I am.
