I do not have a certifiable source for this info, but I can add that in my work in fish hatcherys galvinised metal was a big no no in the tanks for the reason that zinc leached from the metal in contact with the water and was deadly to the fish. I do also know that overdoses of zinc (more than 30 milligrams per day) are harmful to the human body (we are not able to process/eliminate it). so the idea is not rubbish, and caution should be exercised untill conclusive proof can be found. aaron cobmailbox at yahoo.com --------------------------------- Yahoo!
