@Will - That's wild, I get a couple more hours of evening sun than you, however, your pool is much darker than mine, still think it might be calibration, but then you said it "feels cold" too so maybe not. I started at 81 this a.m. and when I turned on the solar at noon I was at 85. Wouldn't normally have turned it on but I have guests coming in town tonight that don't like cold water so it looks like I'm spending a couple days at 90![]()
Let me know if you want to take me up on coming by with my Thermapen and seeing if your off and help you calibrate it.
Larry I will definitely be taking you up on that, going to Cali again but I will call you when I get back. I appreciate all the help you have given.
My pool got up to 84 today so I'm climbing very slowly lol. And yes my pool is very chilly to the touch
