    The chlorine costs are on the high side due to the pool being large at 36,000 gallons. Not much you can do about that except possibly getting a mostly opaque cover since most of the chlorine loss is from sunlight.

    We keep the solar cover on all the time except when the kids are swimming. Not sure how much more swimming they will be doing this year, temps at night are getting in the 40s. Pool is still staying pretty warm, not sure for how much longer.
