I think what Bang Guy is saying is that if there is no proof that it is beneficial and no proof that it is not harmful either that he would rather not add it if he can't adequately determine with commercially availabe test kits that he is keeping it at NSW levels. Until there is hard evidence one way or the other then in reality we are all taking a risk by either adding or not adding it The other point though is just because it's needed doesn't mean it can't be bad. You can actually kill yourself by drinking too much water but I think we'd all agree that we need some of it.
