Rockwork collapsed. Had to rescape. Thoughts?

Rockwork collapsed in the 29. Redid it. Open to suggestions and criticism

If you can live withit the wayit is then leave it alone.
If you aren,t happy then remove the collapsed pieces glue them together with cyanoacrylate and put them back.
Use some rock sand at the joint spots to hold the pieces together
The glue dries fast and is the stuff we use for frags so I don’t see an issue.
Note: that would be my last choice.

Make sure the rocks are on the bottom and not on top of the sand. Otherwise history will repeat itself.
