Yep, heard of it. Actually, there is a FS that I go to and they have a "propogating" tank where they grow nothing but expensive rare stuff and most of their stuff is grown there along with other tanks. Anyway, he places all the stuff that he uses for that particular tank in the front and he happens to use the Vital + Black powder thing by Marc Weiss. You should see his tank, it's doing extremely well.
I've also heard that the blackpowder will "expedite" growth in zoanthids. I've heard nothing but good things on it. It must work. I say try it. One guy told me all you do is sprinkle it on the coral. My guess is that they absorb it in some way. He also told me you see results very quickly.
