Thanks David,
If it is what I think it is, it might be beneficial to have.
I've been doing some research and people actually are buying this. At first, I just wanted rid of it. I've thrown a lot of it away in the past. It seems to do very well in my tank. I think I need a Tang to help keep it under control, though.
There's just too much of it.
From what I've read, Tangs really like it.
