I started running a some carbon a little after brook incident and have never seen the water so clear, and the rest of the tank corals mostly soft are looking great. Just waiting on fish date Jan 4th their about.
It's a long time isn't it?
Just be careful - lot's of folks run fallow, then go out and buy an infected fish and things start all over again.
You should focus on buying pre quarantined fish, quarantining them yourself, or buying tank raised fish that have not been mixed in with wild caught fish.
