I was going to remove the dirt from the sides of the pool as recommended here to prevent rusting. This is what I found.
This is what the floor has been looking like this summer which at first (2 summers ago) we thought were moles/gophers but with more of whatever is going on, it's beginning to look like we are having other issues..
These are directly across from each other and line up with the supports we can see on the outside wall.
Do I continue to remove the dirt or put it back? What would I be mentally preparing ourselves to do next spring?
