Hard water, which is water with high concentrations of hard minerals such as calcium and magnesium, affects the cleanliness of your laundry, dishes and body in a negative way. The hard minerals in the water bond with soil particles and form insoluble salts, which makes cleaning with hard water a chore, as the insoluble salts are very difficult to remove. Heated hard water leaves behind limescale deposits, which can reduce the efficiency of water boilers, hot water heaters and pipe works. Products like Marlo Inc.'s water softener systems soften hard water by removing the calcium and magnesium.
Fill the brine tank with water until the water level reaches 2 inches above the salt platform.
