Ramba Bamba Posted July 19, 2021 Share Posted July 19, 2021 Hey guys, a friend gave me a bunch of lava rock from his front yard. He has used an herbicide in his yard but not directly on the rocks and is pretty sure he’s never used insecticides. Just to be safe how can I thoroughly decontaminate these rocks so that they can safely go into my shrimp tank? Link to comment Share on other sites More sharing options...
