Hello. I have a 27rd beaded above ground pool and I am fixing to replace the liner. I have a sand base and had a sand pool cove but I removed the sand pool cove. I am going back with a gorilla pad and wall foam and pool foam cove. My question is, is the foam pool cove enough for the beaded liner I'm replacing being its smaller or do I need to add sand to pool cove besides pool foam cove. Also can someone tell me the steps on what to lay first . Thank you in advance. Any information would be great
