@ease Replacement SmartChlor Chlorine Cartridge (3 pack)

Frog @ease SmartChlor Cartridge works exclusively with the @ease Floating Sanitizing System. The SmartChlor Cartridge lasts 3-4 weeks depending on tub size and use. Each box contains 3 replacement cartridges. Directions When the floating system flips over, replace the SmartChlor Cartridge by rotating the two cartridges until the arrows align and pull apart. Drain the water from the old silver SmartChlor Cartridge and shake slightly to see if it is empty. Follow disposal directions and replace with new silver SmartChlor Cartridge. Do not discard or recycle cartridge if a small amount of chlorine remains. Place in hot tub to float on its own until completely empty.
