The Simplus System from Master Water Conditioning Corp. uses a manganese-based filtration media to oxidize and then trap the precipitated sulfur. The system automatically starts a regeneration process of backwashing and then rinsing to remove the precipitated sulfur. The system's tank accompanies the filter to occasionally introduce chlorine into the unit during its regeneration cycle to clean the media. The polyglass tank is guaranteed for 12 years.
