Solar covers. 5th pool summer coming up down here in Tucson, AZ. Used the solar cover provided by builder religiously. I have a rectangle with a couple stair/ledge cutouts so its really easy to pull/place. Our back yard gets sun the entire day and has no shade. I would just fold it a bit and leave it off to the side. Surprisingly the initial cover lasted just around 2 years here. Bubbles started deteriorating though and had to replace. I bought a roller which made off and on MUCH easier but think made longevity much worse due to the tightness and increased heat (maybe). Second cover only lasted one year and then same with the next. I'm waiting to buy the next one until I'm actually going to use it this spring but is there anything that anyone has figured out to shade or extend the life. I know pool chemistry can wreak havoc on them and keeping out of the sun when not on the pool is the best idea but i have nowhere to put it conveniently. Especially now that its on the roller.
