We have high iron and copper in our city water. Our indoor Swimex pool was always stained a little brown until I began using this product recommended by the pool company. Works beautifully. We add it every time we add water! This is product is hard to find, so it is great to find it here. Quick shipping, well packaged. Sarah May 17 2016
