Re: Black Beauty Sand
Gee, I can't believe they sell this stuff in a *pet shop*. I have a bag at home
that I use for sandblasting (which is what it's normally used for). Since
there have been a few posts about it lately, I decided to take a close look at
the stuff. First, the particles are *really* small (finer than regular masonry
or play sand). Second, I don't think I'd like the looks of it in an aquarium.
Third, since it's used for sandblasting, the particles are *sharp*. Fourth,
since I knew it was slag, I figured it was high in iron, and, sure enough, it
is. So I don't consider it inert.
I remember seeing some gruesome data on Black Beauty recently, so I
searched the APD. In case anybody missed it, here's the post from Jon
Wilson made on Mon, 17 Mar 1997:

It just doesn't sound too appealing. I think I'll stick to quartz.
