The Spa Frog @ease SmartChlor Cartridge Refills (6473‑193#) are designed for use with the @ease Flip‑Over Floating System. These cartridges deliver SmartChlor® Technology, a self‑regulating chlorine solution that maintains consistent sanitizer levels without daily dosing.

SmartChlor releases chlorine only when needed, preventing spikes and dips while keeping water clear, clean, and comfortable. When the cartridge is depleted, the system flips over—letting you know instantly that it’s time for a replacement. Perfect for spa owners who want dependable sanitation with minimal effort.
