@Humblefish well one positive of this whole thing is, as healthy and non-indicative my clowns have been showing disease, within hours of getting them to the QT they started twitching, scratching on the PVC in the tank, so that lets me know the DT had a major problem, my only sure fire indicator thus far. In an "emergency" (though I planned to go the CP route) I made the executive decision to start ramping up copper immediately. I gave half the recommended dose tonight, will test tomorrow and proceed, despite not all DT fish being in QT I feel I'm at the point of save what you can while you can and figure the others out as I go.
The only locally available copper in a pinch was the Kordon stuff from Petco, which again through reading your posts differs from cupramine in its effectiveness/safety but I felt I had to act quick and had no choice, it's as if they were immune to it in the DT being comfortable and took capture to show.
I'm very committed at this point to figuring this out for long term success. I've had mixed reef tanks in the past and never had to deal with this and know I dropped the ball not QT'ing from the get-go but this whole thing will be a learning experience and wake up call for me in a very positive way.
I already told my girlfriend our date night tomorrow is most likely going to consist of essentially breaking down an entire tank to get the remaining fish out, and re-aquascaping, thankfully she's fascinated and onboard.
I only cross my fingers at this point that it's not something that requires complete tear down, bleaching and reset, because after what I've taken on and invested, I'm not sure I can withstand that.
Expecting the worst, hoping for the best.
