Good putty

[Teenreefer15]

Im looking for a putty that can hold rocks together and also attach a frag to the rock. My corals will fall off the rocks once in a while and I want to attach the rocks together just in case so they don't fall over.

I use JB waterweld for attaching frags, I would assume it to work just as well for rocks.

http://www.amazon.com/J-B-Weld-8277-WaterWeld-Underwater/dp/B000BRQ0TW is that it?

Yes that is it. I like to make a putty ball, a bit of super glue on either side. attach to frag then put in place. I would do the same with the rock.

This is good for frags, but don't expect it to support much weight. A little in the joints is fine, but drilling the rock and using plastic dowels is much safer.

Good point cloak, I was not thinking of arches or anything like that.

Jb waterweld held rocks on my back wall and overflow without having to prop them up. Largest was a little over 1 lb. I also used the sandwich technique, crazy glue/putty/crazy glue.

Leaning is a little different.

Yes. (gel)

I'm probably gonna try the instant ocean putty first

By far my favorite is the D&D putty. It's a bit slower to set than some others, so temporary support is needed, but it holds well.
