While I am sure that reefkeeping.com appreciates the multitudes of free advertising you are giving them in all your posts that you have referenced that article in, can you base your statements on any personal experience that you may have? I can tell you from my experience in my 8 tanks, ranging in size from 40 to 175 gallons, that over the years, I have not had any parasitic issues. I am also adding stock from various sources on a regular basis and have the opportunity to acquire aforementioned parasites that you keep referring to. Although your intent is good, you need to understand that in this hobby, there is not just one way to do things. There are many variables and the success/demise of the contents of a tank, hinge on many factors. Please quit ramming that magazine article down our collective throats.
