@slam level for your cya) -after the water is below 60ish degrees on a regular basis , Open Early - before the water is above 60ish degrees.

I use it all winter & i pump it down pretty much bone dry by setting a brick on it & moving it around to the puddles before removing the cover. A good sunny day or two dries it up well.
Periodically through the winter i use the leaf net to remove debris from the cover as well.
If u set it & forget it you’ll definitely have to pay at opening. A little attention throughout the winter goes a long way.
