Fallow After Brook Outbreak

Hi Everybody,

I screwed up my QT protocol and caused a ridiculous brooklynella outbreak in my DT. My question is two part:

First, since a couple fish survived, how long should I wait before adding new fish? I.e. I would assume since there could still be a risk of them catching it, the fallow period should be extended based on the lifecycle of the parasite. My plan is to wait 4 weeks from the last death, then add the recommended 6 week 'fallow'; thus making it a 10 week waiting period in total.

Second, how are corals affected? For example, I have several which need to be fragged back, so I'll hang a frag rack, and they should be safe to move into other systems after the 10 week waiting period?

As a slight aside, I also need to move some corals INTO this tank, these corals have been in an isolated environment for at least 8-10 weeks (August 24 was the last time I brought a new coral into any of my tanks). Actually, having written this out, I'll wait until the 11 week mark (next Friday) just to play it super safe - although they are cohabiting with other fish right now...

Thanks!

For brook, you need to go completely fishless for 6 weeks, and treat any survivors in a QT. Even though they may not be showing any symptoms, those fish could be asymptomatic carriers capable of infecting any new fish you add. Especially clownfish.
