Here's a link to my old thread about MV nasty stuff.
http://www.canreef.com/vbulletin/showthread.php?t=51938 I have pic's maybe a video of what it looks like in the final stages.
FYI some fish are immune to MV and even if one fish is left in the display and doesn't show signs of MV it can be a carrier of MV and when you reintroduce the fish you were able to treat they could catch it again. It took 2-3 weeks before signs were noticeable in my tank. I also didn't want to tear down and catch everything at first and lost a lot of fish I probably could of saved if I had acted quicker
Here's a link to my photobucket MV pic's and video
