Imminent crash...

[ogopogo]

Hey guys, so my friends tank is crashing... fast. Dead coral, loss of fish, inverts seem to be fine though. Well he has a nice brain coral thats not dead, But not doing well. We have narrowed it down to the wrong silicone being used to make his baffles in the sump and thats why things are dying.
My question is, If I take his brain coral and try to bring it back to life in my reef tank (15 months old and stable) will it leach anything in to my tank and cause a potential crash as well?
Thanks!
