Terry, as you are in the Dallas/ Ft Worth area, I doubt that you need to winterize your pool if you'd prefer to keep it open. I tried to search for posts by those that don't close their pools for the winter, but ended up with 100s of posts which a quick look through showed to be unappropriate to your ? (I used the wrong key words) I just don't have the time to reread them all to cull out what you need (sorry). I did, however, answer a post earlier today about not closing a pool http://www.poolforum.com/pf2/showthread.php?p=40397, mahaps you'll find some useful info there.
What I'm going to do is ask Aylad to take a look at this thread, she's a moderator and doesn't close her pool, so will probably have some more specific advice to give you (knowing when to pass off a question to someone who is more knowledgable is one of the keys to doing well on the forum - though the ego takes a small 'hit' )
I truely! wish you well with your pool and if I can ever be of more service to you, just let me know. - Ted
