How many times have you thought, “hot tubs are just too much work?" We set out to change that with FROG @ease to give you that “ahhh” feeling of relaxation and peace of mind. FROG® @ease® Floating Mineral Sanitizing Spa System combines our sanitizing minerals with SmartChlor® Technology to kill bacteria two ways. Creates crystal clear, soft water for hot tubs up to 600 gallons Kills bacteria and the result is Fresh Mineral Water® Unlike dichlor, this is slow dissolving Uses up to 75% less chlorine with no frustrating yo-yo chlorine levels Only shock the water once a month Easiest water to maintain because it's self-regulating: the system knows when more sanitizing power is needed and automatically delivers it Maintains a consistently low chlorine level for weeks at a time When the SmartChlor® Cartridge is depleted, the system will flip itself over as a visual reminder to replace the empty cartridge with a new one Recyclable when empty No constant monitoring No mixing chemicals EPA registered Maintains a consistent 0.5-1.0 ppm free chlorine level at all times Single color match for easy reading - exclusively with FROG® @ease® Test Strips (sold separately) Kit Includes: (1) Floating System: Mineral cartridge lasts 4 months and SmartChlor® cartridge lasts up to 4 weeks (30) @ease Test Strips: Easy one color match tells when the SmartChlor® Cartridge is empty - also tests for pH, Total Alkalinity and Calcium Hardness to help you maintain water balance (1) Frog Jump Start: Start-up shock for a freshly filled hot tub - effervescent action helps the shock dissolve faster This product is considered a "hazardous material," is air-restricted and cannot be shipped to Alaska or Hawaii.
