Use of Morton® Potassium Chloride Pellets will not harm the resin beads. However, if your raw water has a high iron content of over 2 ppm, you may want to use Morton® Clean and Protect™ Plus Rust Defense™ Pellets. This product contains a resin bead cleaner which will help prevent fouling of clean or new resin beads. Morton® Clean and Protect™ Pellets also contain two food grade resin cleaners that keep resin beads from fouling if your water contains less than 2 ppm of iron.
