Question: Black diamond

[Toy]

Is Black Diamond Blasting Sand safe to put in the tank? I would prefer to use black substrate if possible. I have a golden an albino and a wild type. I think it would look good behind them.

BUT IT'S IT SAFE?!?!?!

No. By definition the grains are rough, and it is often contaminated with other stuff.
