Was just thinking about the following after reading gizmos, noodles..... Does the gizzmo or jug or what ever is being put into the skimmer for winterizing, does it have to be tall to reach almost to the skimmer cover. I see pools with a deep skimmers and the jugs sit quite low on the bottom. Is the protection only till the top of the jug or even the 6 or 8 inches above the jug height where the jug would not penetrate the ice when the pool fills from rain or snow and then freezes.
