Crystal Quest Eaglesorb Anti-Scale is a saltless, non-chemical, hard water treatment medium. When using Eaglesorb ES3, nothing is added to the water. Calcium carbonate crystals formed by ES3 remain dissolved in water. ES3 prevents scale buildup and dissolves the previous buildup. ES3 eliminates scaling on the surface of heat sources, fixtures and appliances. Pre-treatment is required for iron, manganese, copper, oil, hydrogen sulfide, phosphate and chlorine above 3 PPM.
