I read an article today from saltwater.about.com, regarding a quarantine process that starts with hyposalinity and a couple of rounds of preventative medications. I have attached the link here and am interested to see what you all think. The basis is similar to the analogy of preemptively worming a dog...I know, fish are not dogs...but it seems to make sense. Thanks for your feedback. http://saltaquarium.about.com/library/blank/blaggressiveqt.htm
