Frog Ease Chlorine Cartridge Refills for Hot Tubs!

Fresh Mineral Water with SmartChlor® Technology in one floating system!  Blue Mineral Cartridge and Silver SmartChlor® Cartridge snap together and float in the hot tub.

The unique SmartChlor® Technology slowly releases over 3-4 weeks. When the system flips over it is time to replace. 3 replacements per package. For use in any hot tub up to 600 gallons.
Up to 75% Less Chlorine Usage
Only Shock Once a Month
SmartChlor® Self Regulates for Continuous Clear Water
The SmartChlor® Difference:
With SmartChlor® Technology, there is always a reserve of chlorine waiting to be used. When needed the reserve automatically converts to free chlorine which maintains a consistently low level.

Dichlor tabs tend to have yo-yo chlorination while SmartChlor® Technology keeps the free chlorine in the 0.5 to 1.0 range at all times.
