This is our first year with our new pool... we bought it from family friends with a great deal! However, the pool did not come with a cover. Neighbors had an older solar cover that we've used for the time being but wondering if there's other style suggested? We don't mind the solar cover, just want to keep water levels under control annnnd the solar cover we have is a little bit too small for our pool so it kind of defeats the purpose as a cover. We have an intex 18' round pool. Any help is appreciated Thank you!
