Diamond Crystal Iron Fighter Water Softener Salt Pellets are specially formulated for homes with high iron content in their water supply. Iron in water causes rust stains on laundry, fixtures, sinks, and tubs — and these pellets are designed to combat exactly that.

Each pellet contains up to 99.6% pure salt with an FDA-approved additive that actively prevents rust stains throughout your home. The formula is virtually 100% water soluble, which minimizes mushing, bridging, and rust buildup inside your water softener's brine tank, helping to keep the system running cleanly and efficiently. Recommended for most types of water softeners, and particularly well-suited to regions with naturally high iron water content.

The 40-pound bag features Diamond Crystal's patented two-handle design for easier lifting and carrying. The product is NSF Certified to NSF/ANSI/CAN 60.
