Prazi-Pro is added directly to the water either in QT or in a FOWLR. I wouldn't chance using it in a Reef system. You should do back to back treatments with a water change between the first and second treatment. Metro comes in diffrent brands/forms, I have personally used http://www.seachem.com/Products/product_pages/Metronidazole.html
and it has worked on several fish. Not to be a downer though, but when my Goldflake looked like your Trigger, it eventually passed.
Thanks Jason.
