    Proteam Metal Magic is also HEDP (1-Hydroxyethylidene)di phosphonic acid), It is a metal sequestrant and also used as a corrosion inhibitor in many industrial applications. It keeps the metals dissloved in your water from depositing as stain but does not do too much to existing stain in most cases.
