Gorrilla Glue Good! Epoxy bad!
I used it in Trapper's tank and on 1/3 of my 4' live rock wall. If I had started with it on my LR wall it would have taken a day in stead of 2 weeks (in the tub w/sw) and would have stayed together much better. It dries in about 4 hours. Be careful if you use it in a wet tank (yes, that works but don't use it in a populated tank) because you will get a scum that could stick to your tank walls (it is messy). A piece of paper towel draped about 3" into the water will take care of any issues and the scum dries quickly and lifts out without a problem.
It is my very favorite glue when pretty is not a concern. Be aware that it will expand and bubble but it still looks and holds 1,000 times better than epoxy (moving your rock around afterwards is not an option).
