Today I helped a friend clean out her old saltwater aquarium. It was not properly maintained and really gross. She had two large live rocks and she gave them to me. The rocks are goregous, but I don't want to put them in my fish tank for fear of some disease or something. (last time she had fish they werent sick...but the tank was disgusting when we cleaned it) I put them in a bucket with saltwater and a heater. What should I do? How long should I wait before putting them in my aquarium? Please help!
