Thanks for the reply. I will try the rock salt idea. I was thinking of Round Up, but not sure how soon after using it I could cover it with the ground cloth. Its just a blue plastic tarp.
I knew about using rounded endges with the patch. I wasn't sure if it needed to be on the inside or both, in and outside. We'll do it before adding the water. I really can't wait to get it out and up and us inside of it. But 45* is still to cold for me. It's not a big pool, but I really like having a float and a cold beverage after a long hard day working, and this works for us, right now. Thanks guys, Kim
