Keep your swim spas and hot tubs in great condition and ready to use with the FROG @ease Floating System that combines SmartChlor Technology with FROG’s patented Minerals. The sanitizing minerals last 4 months and the SmartChlor Cartridge lasts up to 4 weeks depending on hot tub size and use. The hot tub sanitizing system floats when working, flips when empty, and is ideal for hot tubs up to 600 gallons. FROG @ease uses SmartChlor, a patented chlorine formula that adds a low level of chlorine only when needed. Combined with FROG Minerals, FROG @ease creates Fresh Mineral Water for continuous crystal clear water and peace of mind when it comes to hot tub maintenance. With FROG @ease, you use less chlorine, making the water easier on skin, swimsuits, and your hot tub’s surfaces. FROG Minerals clean organic contaminants, condition the water for softness, and absorb acid to help keep pH balanced. FROG @ease has its own hot tub testing method that’s much easier than other test strips. One color match on the FROG @ease Test Strips easily shows when the SmartChlor Cartridge needs to be replaced. For more than 25 years, FROG has sanitized pools, hot tubs and swim spas with its innovative, patented Mineral Technology that makes water care easier. FROG's prefilled cartridges mean no mess, no guess, and no stress pool, hot tub and swim spa water care. Each FROG product helps make your water Cleaner, Clearer, Softer and Easier.
