I am Assuming my above ground pool should be covered for the winter.
Here it is not uncommon to get -5 to -10 below for awhile. but mostly 10 to 25 degrees Fahrenheit in the winter.
What are some of the features to look for in a winter cover?
Thickness, Oversized to hang over by how much?
What is the pillow/ball thing for that I see occasionally poofing up a pool cover?
Is any heat source needed during the winter ?
What is to be done by accumulated snow or water? drain it off or leave it to keep the cover from blowing around?
Teach me please.
