The Dow "Great Stuff" works great for this. Any hardware store will have it.
I used about a case of it to secure a filter bed under a 2000g exhibit. The took the tank down 2 years later and are still cursing me. They had to GRIND it out.
I like aragocrete for this too.
Both are reefsafe when cured.
