The @ease system by Spa Frog is the latest and greatest in spa sanitation technology. It’s the world’s easiest water care system; the chemicals come in cartridges which automatically sanitize your spa water. The only thing you need to balance is the pH.
This is the inline smartchlor cartridge; Only use this if you have a Spa Frog inline canister installed in your spa. If you don’t have one, there’s no need to worry; you just need to get the floating version
For use with the following spa lines that have the “Frog Inline Canister” installed. Should always be used with a Frog Blue Cartridge.
