super glue gel

Just wondering what everyone uses for to keep their rockscape together. Do you use putty, supergel or just stack? Doing a new scape for a build so looking for recommendations.if you don’t mind please let me know brands. Thanks in advance!

I think I nailed it first try, is that even possible? Now I took lots of pics but should I also epoxy and glue pieces that I can to make sure I can get it back this way in the cube?

Has anyone tried to epoxy or glue small pieces of rock rubble to the tank glass to support corals that need to be separate ..... also directly to the bottom glass for rock stability in the build of a new aquascape and which product was successful, gel or 2 part epoxy
