looking for reef friendly repair glue.

[Douglas]

I'm looking for a reef safe glue. I'd like to use, to make a repair to my tank. A section of egg crating, i had glues around the edge of my overflow has broken off. Is there a "reef safe glue" i could use to glue it back on? It was siliconed on, at first, but the tank is now running, and I don't know if silicone is a reef friendly glue, once the tank has been established and running.
