for anyone questioning the impact of a solar cover

interesting..what the air temp was during the day for you...on the hot summer days i could see that..now that it's like 68-70 for a high with the cover on the temperature has maintained but not gone up..i know what you mean about the crud on the cover, but i prefer that to in the pool..i have my solar reel rigged with ez-grabbits on the one end so it really is a one man job..if i had a bigger pool, i might not say that (mine's 15 x 30 inground kidney shape)

I know what you mean about the crud. We kept dumping it in when the wind blew as we were rolling it up. My skimmers {2} are very well placed for collecting off of the surface water.
The pool itself is 20 x 44 lazy ell with grecian ends. A very clumbsy dimension for the cover.

By the way, Sunday night the air temperature went down to 52 degrees. At 8 AM the pool water was 72 degrees, a 9 degree loss. My theory is that the pool structure below the water acts as a bit of a heat sink. Once the gas heater is turned off, the structure begins to return its heat to the pool water, slowing the heat loss. But it certainly does lose heat faster over time than with a cover. Under the above conditions, we probably will only swim in the pool one more time before we close it.
