Package of 3 @ease Smartclor Replacement Cartridges for the @ease floating system. The Spa Frog @ease Floating Sanitizing system is one of the easiest ways to keep your hot tub water looking clean and clear while keeping chlorine levels to a minimum. If you are using the @ease floating system then you need to replace the Smartclor cartridge every 3 to 4 weeks depending on use and spa size.
This package comes with 3 chlorine replacement cartridges. With the floating system your cartridge floater will flip over when empty. Meaning the grey cartridge will be on top and the blue will be in the water on the bottom. Also remember to change your blue mineral cartridge every 4 months.
