It's hard to know what might leach out of them; probably better to go with actual stone of some kind.

I would stay away from patio stones, as some are sealed from the factory and  some are mixed with stuff thats notfish friendly.

go with fieldstones natural stones or slates

 You can get sandstone pretty cheap from a landscape place.

Try Angelos on 8 Mile they have some nice sand stone.
