sorry to hear that, any way to test if it is pyrite?

I dont know, I am pretty sure it is though. I have only found it on one piece and its a very small ammount. The rocks have been in the tank for months now.
 
Looks like it to me. I would still at least call your store and talk to a manager. Just tell them you just realized it was there and found out it was harmful.
 
they theoretically can give you maybe some store credit or something if the manager is sympathetic
 
Thanks for the advice guys. So even though the other pieces of slate don't appear to have to pyrite it could still be there inside somewhere, so how do I ever know if any rock is completely safe?
 
If the color is true, that does not look like pyrite. Pyrite would have more of a yellow hue due to the sulfur. Those look like they might be quartz or silicate crystals in the rock. All of the pyrite samples that I've seen have not been in veins. If you wanted to be certain, you could put the questionable piece in a bucket of neutral water and monitor it for pH drops.

The color is pretty close to how it looks in real life. Its like a kinda dull gold color. Well that particular piece has actually been in my 30gal tank for a few months. The ph has remained steady at 7.6 the entire time.

Also on the other side of the rock there are some other granular minerals that are rust colored.
