We've ordered from three different wholesalers for both batches, and I venture to guess they supply about 75% of marine fish. I don't want to name any names, but we haven't isolated it to anywhere. You could be right, however.
Just want to suggest - that having 3 different wholesalers simultaneously develop resistant strains (strain) of velvet would be highly unlikely - unless multiple other people were reporting the same thing at the same time. It suggests that perhaps there was an error in copper dosage or some other cross contamination? I know you guys are careful - but the fact that this hasn't happened before - (in any of the research I have seen - as I said except 1 poster session from 2011) but now has occurred from 3 different places makes some kind of problem with your QT process more likely (or?).
