I am losing a lot of "heat" during the evenings. During the day our water temps get up to about 82 deg (if sunny and air temp is 75 or so). At night we put on the solar cover and the intex cover that came with the pool. By the morning, I have lost anywhere from 8-12 degrees!! I do not have the money to buy a pool heater so that is out of the question.
I thought I read something about using foam board on the water surface to help insulate in the evenings. If so, I would try that and put it on after the solar cover and before the intex cover.
Does anyone have any suggestions?
