The Frog® @easeTM In-Line System with SmartChlor® Technology maintains crystal-clear water automatically. Pre-filled cartridges eliminate the guesswork and combine chlorine and minerals for carefree, self-regulating sanitization and balanced pH. Chemical odors are minimized because you’ll use up to 75% less chlorine. Minerals condition the water for a softer feel.
The @ease SmartChlor and Mineral Cartridges fit out of sight, in the spa’s filtration system,and chlorine is released slowly to maintain more consistent levels. Simply set the dial on the cartridges and insert them into the spa. Chlorine cartridges last up to 4 weeks; mineral cartridges last up to 4 months.
