How Do I Remove Metal and Stains From My Pool?

[rusty37]

I am preparing to start installing my AGP as may know if you saw my first post, but here is another question. I am on well water so I will have a truck fill the pool. Problem is with keeping the water topped off, I would have to use our water. In the past we had tried a couple of different "easy up" style inflatable pools and filled them with the well water. As soon as chlorine was added the water turned heavy yellow and would stain your bathing suit. I believe the chlorine was bringing out the iron in the water.
Since I know already I cannot use chlorine what would be an acceptable substitute?
