That is great guys! I tried searching for old threads, but never found what you posted Adirondack Pond. That is what I bought esshup, 1" PVC pipe and fittings and 1/4" mesh.

I was thinking of putting some fine sand in the bottom frame row only. Maybe just the holes will be enough. If I leave the top sealed, it will trap air and make it more buoyant than the bottom section. Perhaps a couple of pool noodles strapped to the top will help as well if needed.
