I have a question on my pool cover. I have an L shaped 33,000 gallon pool with a cover that snaps into the liner. After putting it in then you go around the edge of the pool and snap this rubber stuff in place to secure so the liner stays in place. I hope this makes sense. I can't find any information about this kind of liner online anywhere or the rubber material that you snap it in place with. I need some more of the rubber stuff bottom line. When I get home I'll take a picture if nobody know what I'm talking about. I do know that this kind of cover is a pain to put on when closing.
