HELP... My rockwork collapsed

[Dj City]

I have had this tank set up for 5 years and I liked how it WAS set up but...

I have a LARGE carpet anemone and a LARGE maroon clown.
The clown decided to try to move corals and rocks. I came home yesterday to large rock on the sandbed.
and a large monticap on the sandbed.
I tried to put them back but the whole structure shook and I had to move everything on that side of the tank.

My question is...

Is there anything I can buy local at like a Lowes or Home Depot to cement the new rock structure that I have to build?
I don't want to wait to order from BRS. I just want to get this done and would be happy to just go to lowes and get this project completed.

Super glue gel will do, but you’d need a lot of it.

I have way more rock than superglue will be able to handle.
The entire right side of the tank needs to be redone. Everything right of the overflow collapsed.

I read somewhere that hydraulic cement works. It it reef safe?

I will be taking all the rock on the right side of the tank out, creating a structure that I like, cementing it and putting it back in and adding the corals to it.
Corals will be added with superglue but the rocks need something better than superglue.

I used super glue to start the hold. Then used epoxy around the joints.

Hydraulic cement will work. As far as reef safe it's risky. I wouldn't recommend it in an established tank. It will definitely screw up your PH and probably your Alk. It would be best if you could build your structure and let it cure for a week or more in a different container of saltwater. You may be better off using driveway marker rods and drilling your rock. Just use some epoxy stick in the holes with pieces of rods to hold them in place.

Well since I have to rescape the right side of my tank I figured I would build an overhang.

I used hydraulic cement to put 3 pieces of rock together along with attaching the structure to a base.

I can build on it from here if I like it in the tank.

And this is the new and improved aquascape.

It looks like I have two tanks in one. Left side is densely packed but beautiful.
Right side is spacious, airy and beautiful.

If I can find a balance without destroying the left side,
That would be great.

Either that or get used to the new look.
