Anyone tryed using powdered iron slag?

I just found an article i read awhile back. i was wondering if anyone has used iron slag or powdered iron slag.

heres the link http://www.cichlid-forum.com/articles/sand.php

Wouldnt iron slag contain lots of heavy metals and such?

It's very possible that the slag is contaminated with heavy metals.

We use Blackbeauty to sand blast paint off of equipment. The Label shows it as inert and non hazardous, however the grains tend to be sharp and angular. I think that Tahitian moonsand is the same thing.

I have used Black Beauty for substrate and it looks good and is a pleasure to plant in. As Urkevitz mentioned, it wouldn't be good for Cories, Loaches etc due to its sharp edges.

I could take a pic, but I would have to look for some in my garage I replaced it with Flourite to see if a "Hi-tec" substrate is that much better. Not...

Exactly how sharp? Well, imagine broken, black glass particles, all in one size.

You can get black beauty in differant particle sized, maybe the larger ones are less sharp. When I look at Tahitian moon sand I see some particles which are cylindrical in shape, Black Beauty has cylindrical shaped particles also. It makes me think that Tahitian moon sand is manufactured.

My 100# of play sand fizzes when i pour vinegar over it.... Would it bring my ph down too low to use in a planted tank?

I have not yet seen moon sand, mine will be here tuesday. Im not quite sure what moon sand is. but it could be crushed hardened lava?

Actually, when it fizzes, frizzles or snizzles, most likely there is some stuff in the sand which will raise up your pH (buffering by calcium carbonate).
