Fluorite black sand and crs?

Is fluorite black sand ok for a 5 gallon crs only tank? I've heard it can have copper in it?

Flourite is an enriched plant substrate, so it contains nutrients. 14 nutrients according to Seachem who make it, you can see the list here:
Seachem. Flourite Black Sand

This substrate is intended for aquaria and the minerals are not in sufficient quantity to harm fish or invertebrates. Plus, they are only released as plant roots need them, according to Seachem, and are assimilated by the plants and not released into the water column as such.

Thanks Byron,

yeah my LFS told me it should be ok but wasn't 100% sure so told me to check out the forums LOL Is it possible that shrimp can die from it while grazing on the sand floor for food and digesting tiny tiny traces of it? I know it sounds a little weird but that's what someone told me.

I can't answer definitively, but I would not think so. The shrimp are not "eating" the substrate, any more than my corys are eating the Flourite substrate in my 70g.

Plus the copper in substrates and fertilisers are chelated, which makes them totally safe.
