So i understand the purpose of the pool pillow. To keep the cover off the water and help make a peak in the cover to shed snow and ice.
I heard of pool walls buckling if a pillow isnt used...When the pool freezes, the ice pushes out on the walls. And a pillow prevents this by allowing the ice to use the pillow as a sort of sponge.
Is this the case? I hadnt planned on using a pillow this year, but if i need to, i will.
This is my first year closing my own pool. I've found in the past...years ago, my parents used a tractor tire inner tube on their pool. I've even seen people use old tires in their pool before.
