    So after me getting a rock that was not safe for my tank I desided to go to the near by lake for a nice walk with my dog and I came across 4 rocks that seem to be safe for my planted tank. I wanted to know how do I go about cleaning them, I scrubbed them with some hot water and boiled them for couple of hours is it enough or do I need to do something else with them?

    I also not sure what they are I tried to identify them but I am not sure if I am correct with what I came up with. I am attaching a picture of them and if anyone can tell me what they are or if you think they not safe for my planted tank it will be greatly appreciated.
    Thank you and sorry about my stupid questions

    #1 This looks like a slate rock to me.... correct me if Im wrong

    #3 this almost looks like a granite but I'm not sure could it be diorite?

    With all you did, your rocks are plenty clean!

    #'s 2, 3 & 4 look safe to me, but #1 would need to have some acid (hydrochloric/muriatic) dropped on it to be sure, in my opinion. If it fizzes, bad news -- just by the look, I think it will fizz. And, since you would be obtaining acid anyway, you might as well drop a little on all 4 rocks.

    Thanks for the reply, I will do the test on all of them. And I'm glad i asked because i thought that #4 looked questionable not #1 :eek:
