Is bubble need during the winter for above ground

[rdefino]

Thanks for the replies.

Now would I have to worry about the sun fading my liner with no cover?

In the winter? In Massachusetts????

I never have a problem.

Thank you. Odd, growing up I was always told a bubble was need to keep the ice from pressing on the inside of the walls of the pool. It gave the ice the ability to push into the bubble being that the bubble is flexible. Any truth to that?

I always thought that as well and it may have been true then. Modern AG pool walls are usually formed in a slight zig-zag pattern that's supposed to accomodate the expansion of the ice.

mmm, is that why my doughboy when looking at the wall from above it's in a wave pattern. the side go in and out.
