Okay thanks!I've never boiled rocks either.... If I found some I liked I would take them home, soak them in hot water, scrub them a little to get any dirt and such off... and then in the tank with them.... although, if you are not so sure about the limestone, vinegar will help you determine those.
Yup, I have heard about the vinegar test before.
Thanks
