This thread is a few years old. There is actually another thread started this week where someone was asking the same question ----- how to manage a large round solar cover on an AG pool.

I used the system explained in this thread for quite a few years and it worked well. But, last year, I ran across a product called a Solar Roller Cover Stick that I now use instead. Here is a link to the product in case someone missed that other thread and is interested in this product.
