It has to be treated like Ich, 4-6 weeks fallow.

However, I have had success catching fish, giving them the formalin bath and returning them back to the same tank. I wouldn't recommend it, but sometimes a person doesn't have much choice. Having to re-treat with formalin would be hard on the fish as formalin is bad stuff. Brook is nasty simply because of the nasty treatment you have to use to get rid of it.
