How to test rock
I know this is a really simple question but, since I've never done it before, I dont know the answer.
How do you test a rock to see if its ok for your tank? I remember reading somewhere that you use vinegar but I dont know how much, or if there is some ratio to water. If you know, help me out please. I have an s-load of rocks around my house that I think would look great in the tank. I just dont know if their safe. Thanks.
