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.
