Bruce,There's not a lot of detail here ... How would you make this method work; more to the point, how can other reefers and fishkeepers utilize the techniques to keep their charges healthy, and assure the health of fish coming out of the "chain of custody" between the reef and their home aquarium? The portions of the article you quote (with much unavailable snippage - where could an interested party read the full article?) seems to distill down to "Cryptocaryon got through our QT process and into the display. A lot of our fish died, but some survived."
Would the same protocols have worked in the case of velvet?
QT isn't perfect - there are humans involved - but until something better comes along, it beats the heck out of "dump-and-hope". Have you got that "something better"?

Here's the article. Found it with a google search.
