The rock is out. In the garbage. This is the rock that I just put up for trade. I wouldn't have given this to anyone after smelling it. Also, the same stench was in my fuge but is gone now following a thorough cleaning and water change. I had the "red crap in the fuge", but it got a thousand times worse after getting this rock. You know, every item I bought with that rock smelled like that even though from different tanks at the LFS. Wondered what that was. As I said, my chemistry went haywire after putting this rock in as well.
