I picked some black River Rock out of my landscaping to use to build some rock-work caves for my Malawi tank. The problem is that these rocks have been exposed to Round-up, grass fertilizer, Weed-B-Gone, insecticide, etc etc every year for the past who knows how many years and as recent as a month or two ago. I'm trying to do what I can to clean them before I add them to the tank. So far I have soaked them overnight in vinegar to check for bubbling, soaked in water overnight, scrubbed them with a baking soda paste and an old toothbrush, and boiled them in water for about 20 minutes, rinsing thoroughly between each step.
Is this sufficient? Do I need to do anything else?
