When I put the pond in the small sulcata enclosure I used a piece of pan liner rubber, At that time I figured I would do something with the edges later, After looking at it and seeing him go in and out without any problem, I am going to leave it as is, Now to clean it all I do is pick the piece of rubber up, let the water fall out on the ground, lay it flat in the grass and rinse it with the hose and then put it back in place and add water, takes about 2 minutes.
