It will keep your water heater from rusting while reducing or eliminating odor problems because of anaerobic bacteria found in some water that react with regular magnesium or aluminum anodes to produce hydrogen sulfide gas and a rotten-egg odor. It’s most likely to solve this problem if a water softener is NOT being used.
