In IL and been open for several weeks . My water is already 80-85 degrees. Have a clear solar cover. My pool sits in direct sun no shade. I know in a few weeks it will fill like bath water if I leave the cover on... even without it seems to get too warm. I like the cover to help keep the dust out and keep chlorine in since I have so much sun. Any suggestions on what to do to reduce the water temp or prevent it from getting too warm? Change to reflective solar cover instead of clear?
