My wife has a beautiful piece of Oklahoma Rose Rock and I was wondering if it would be safe to put into my tank. Here's a photo of a piece:
Here's a link to a wikipedia article that has some information about the mineral content and how it's formed.
http://en.wikipedia.org/wiki/Rose_rock It's really similar to the red stone we have in southern Utah, but was formed when an inland sea retreated.
It consists of barium sulfate (barite) and quartz sand that contains iron.
What do you all think? Could I put a small piece of this in my tank without negative effects?
