From what I've heard DO NOT use gorilla glue, yes it has the right compound, but it also has other chemicals in there that aren't reef safe. I'm 95% sure of this... but would you risk a complete reef teardown over risking using gorilla glue versus $1.00 super glue from the dollar store?
Use the sure thing, risks in reefing can be costly and I'm 95% sure it can cause harm... haven't tested it myself and wouldn't try either though.
