We just bought a house with a pool and are VERY new to all of this, but also very excited at the prospect of having a pool. We're interested in getting a solar cover (we're in San Diego so very low humidity and we've already noticed the significant evaporation (and it's only April!)). The previous owner's pool guy stopped by, looking to continue his account, and I asked him about solar covers. He suggested that if we get one that we only get one to cover about half the pool. The pool is 18 X 38 inground and he suggested a 10 X 20 clear cover. He said it's easy to clean around this and easier to work with/ get on and off with the reel. Any input on this? I can't find this addressed in the forums.
