Without reading the article I can tell you that I have experimented with this idea in the past. Long story short- About a year ago I had some sort of infection wiping out my Birdsnest, then it appeared on my Monti's and then it moved to some of my Acros. They were RTNing pretty fast so I knew I had to try something or I would lose them all. Since Birdsnest is easy and cheap I tried it first and it worked. So, I pulled them out and gave them a short soak in a freshwater fish antibiotic mixed with tank water followed by a soak in clean saltwater to rinse. I did it for 3 days straight and it went away. I did lose tissue but I didn't lose a complete colony. The RTN event stopped on all of them. Technically the first time I tried this was with a brown jelly incident on Acans several years ago. That is truely where this started for me. I knew that brown jelly was easily spread and deadly so I really had nothing to lose. Now, if I see some sort of infection happening to a coral I inspect for pests first, if nothing is discovered, antibiotics dip is next.
