I have an 18x33 oval above ground, one year I used the bottles hanging from the eyelet method, but that ripped my eyelits out. Recently I've been doing the cable and releasing it when it freezes.
I have a few questions:
-I have trouble keeping the pillows inflated and stationary, by spring they are at the bottom of the pool, what other method can I use??/ I was thinking about two thick tire tubes?

-Last year the ice shifted and punctured my liner, so now I have a new liner, and paranoid about another shift, is there a way of preventing this??

-And of the two methods previously used for the cover, which one would you suggest?? bottles or cables??

Keep in mind I live in Massachusetts, which equals snow,ice and more snow.
Thanks
Barry
