Hard and pure. Prosoft compacted salt cubes keep water softeners working at peak performance and extend the life of plumbing systems. Prosoft cubes are tightly compacted from top quality vacuum evaporated salt for extra hardness. These specially sized cubes help eliminate bridging, channeling and mushing. High purity salt. Prosoft compacted salt cubes are 99.8% pure salt and are virtually 100% water-soluble. This means your customers will have less brine tank clean outs and water softeners that operate longer at peak efficiency. With rust buster. Prosoft compacted salt cubes with the rust fighting additive help prevent iron and rust discoloration on sinks, dishes, toilets, cookware and laundry. It cleans iron-fouled resin beds, thereby increasing water softener efficiency. Prosoft's patented rust buster additive is ph neutral which lowers the risk of softener damage. Not all rust inhibitors can make this claim. Rust buster is considered non-toxic to septic tank bacteria and is recommended for iron levels over 3 ppm. Available in 40, 50 and 80 pound sizes, prosoft compacted salt cubes are guaranteed safe for all water conditioners and are effective in both residential and commercial applications.
