Hard water is properly named because it really is hard on things like appliances and plumbing. The Pro Poly Guard System features a 1.5 lb. cartridge with special polyphosphate crystals that dissolve slowly over time and create a protective coating on surfaces vulnerable to scale build-up and corrosion.
