We live in East Texas about midway between Dallas and Houston. We rarely have freezing temperatures. What do you recommend for closing? I have been reading posts about leaving the cover off, running the pump for an hour a day, etc., but I am unsure. In the past I have always done the full cover, had a huge mess to clean off the cover, and usually it all spilt into the pool anyway when removing the cover. If I can leave the cover off I would love it. Please give me the benefit of your TFP experience.
