I found a beautiful piece of lava rock a year ago. And it has been sitting on my porch untill now. I am setting up a new tank and was wondering if I could use it in my reef tank? It has many different colors of minerals on it so I was going to clean it and try to use it. But I didnt know if the minerals on the rock would hurt anything that I will have.:confused:
 
Most people that responded to previous posts on this subject say that lava rock has toxic materials in it that will leach out into your tank. I'm not totally sure if that's true or not.
 
I have heard some people say that is is pretty sharp and can scratch fish that rub against it. fish do that a lot
