I just got back from the Dominican Republic and brought some rock back that I found walking on the beach. Can I put that rock in my established tank or is it not a good idea? I heard if you find a shell on the beach and want to put the shell in your tank that you have to rinse it off. Also you have to put the shell in a can with water from your tank and let it sit because the shell will release ammonia. True or False???? If so is it the same for the rock??
