Dave has a good point. At this time, if you can find water that won't have the same issues as yours, then it may be much easier and cheaper to do this than to spend more on chemicals. The back of the metal magic bottle says it gets rid of mananese too. If you start with metal free water, if there is somewhere you can get it, then you will only have to deal with your fill water, which may be easier - It is up to you.
