I have a mesh safety cover from Loop Loc for my in-ground 18x36 pool. At the end of last season I put in a new stone patio around the pool, but haven't yet re-installed the anchors to attach the cover to the ground. I've got a lot going on right now and don't plan to put the anchors in this season. I'd still like to have a cover for the winter though (however in this case it won't be for safety, but rather for cleaner/easier opening). Any reason why I couldn't purchase those water bags and use it with my cover? Should be fine, right?
