QT time after brook?

[Hal]

I have a Niger trigger that's been in QT for 4-6 weeks. He developed something that I diagnosed as brook; it's difficult for me to tell the difference between brook and velvet, but ultimately I voted brook. I treated him with daily formalin dips/baths for a week, and he seems to have recovered with no more symptoms. He ate great the entire time.

Now I'm wondering how long do I continue to leave him in QT. Does brook have a particular life-cycle that I can calibrate against?

I left my flame angel in a QT for 6 weeks after the series of formalin dips with no reoccurrence.
