@Ease Floating SmartChlor Cartridge Replacement 3-Pack
SmartChlor Technology maintains a consistently low free chlorine level of 0.5 to 1.0 ppm at all times. It does so by creating a reserve that converts to free chlorine when it senses demand on the hot tub. Dichlor’s free chlorine level drops significantly under demand requiring the user to shock. SmartChlor reduces shocking to only once a month!
