Hi Mom, I have used the Gorilla pad. I had a little problem getting it smooth enough for my liking. I am sure with a little time that could be overcome. It sounds like it might be a good way to go. I would also recommend Green Lite ant killer under and around the pool at all times. This stuff is amazing and if you can keep the ants away from the pool there is not much chance they will get under it.

In my 35 plus years in this bus I have only seen ants do damage to a pool on a couple of occasions. It is so strange and so damaging. Once I saw ants eat holes in a liner. Once I saw them move large amounts of sand underneath a pool, huge sink holes.

Hope you get them under control, Dennis
