Unlike traditional chlorine that requires constant monitoring and adjustment, SmartChlor® technology automatically delivers the precise amount of sanitizer your swim spa needs. The result? Softer-feeling water, less chemical odor, and more time enjoying your spa instead of maintaining it.
Compatible with the FROG® @ease® Floating Sanitizing System, this replacement cartridge is an essential part of your swim spa care routine. Whether you own a Master Spas, H2X Fitness Spa, or other major swim spa brand, FROG® @ease® delivers consistent, reliable sanitation.
