Purple slate rock??

[29102016]

Hi guys and gals is it possible to use purple slate rock in my new aquarium instead of reef rock?
This will be predator only and really fancy something different.
Will it leach anything harmful to my fish?
Thanks in advance
Mike

I don't think you have an issue in a fish only
