Mmm, are you (re)placing the fish/es back into the same system they were in?
I finally dropped the S.G. to 1.017 maybe 3 days ago, today’s water change now it’s 1.015. Have not seen white or black spot on either fish. The tang is clean and acting pretty normal. The coral beauty is another story. I found several things on your site warning about copper, and one advising formalin and Methylene blue. Not being a rocket scientist, I figured out the formalin was causing the problems with the coral beauty, but only after a couple of days, during which the fish went pretty far downhill. Today the white patches seem much smaller, it is acting less stressed, but the color is quite pale, and the fins are somewhat ragged. I am now still using the Methylene Blue, and just gave a half-dose of Maracyn to see how they do. Is this a proper course of action?
