Bonding reef rocks - best glue for the job?

[menac]

Hey all,


I am looking to completely rescape my 92 gallon cube and open more space.
I have some flat tonga shelf rock sitting in the closet waiting to be used.


What I am trying to find out is what is the best and strongest bonding glue I could use or others in the reefing community have used to hold their rocks securely in place?
Especially shelf rock.
I know there's a product out there.

Emarco Cement worked great for me and tonga branch

I've used marco cement on some dried out live rock that I had laying around and have to say it is dam near bullet proof. I've tried breaking them apart and can't.

When I used the cement on marco rocks...the bonds were hit or miss. Some of them were strong and are still in my tank, others fell apart almost immediately. Didn't do anything different when making the cement. Never really figured out why those bonds were so weak.

I used Fauna Marin's AquaScape Fix. Pellets that melt together in hot water. Worked really great for me. Its a tad bright white but I plan on encrusting corals over it. I glued 4 pieces together to create my own "branch" and various shelves. Again, worked great and decent price on BRS. Don't need much.
