We closed our pool yesterday... I followed some of the advice, I did buy a new winter cover, air-pillow and all. I just couldn't accept not covering it, sorry! I didn't buy the worthless "winterizing kit" tho, that the pool stealers were selling, don't need it. Just poured in two large jugs of bleach and covered it. Forgot to add the poly-quat tho. Oh well. We'll see if I open green. At least now I know what to do now if it does turn green!
