Nice,,,,Thanks,,

So I am dumbing this down for myself and checking my understanding with your.

Since my pool is an outdoor, AG, In Iowa. I want to both gather as much heat as I can, and keep it in the pool best that I can.

The best "Bang For My Buck" is a clear insulating cover, Not a Solar Cover? Preferably one with a Mill thickness that would allow me to run my pump with the cover on during the hottest parts of the day??

Does anyone have an Insulating cover they recommend??

And hey, If my understanding is incorrect. Feel free to correct me.
