Is there any potential issue with leaving solar cover on for more than a couple of days? It looks like it's going to be cool but sunny this upcoming week so i don't foresee us using the pool much. It's also a 2 person job to put on and take off as we don't have room to store a reel, so it's not always convenient to take it off in the mornings because my wife and I are up and leaving for work at different times. Its a blue, opaque cover. Thanks in advance.
