Keep your hot tubs in great condition and ready for use with FROG @ease Floating System. This floating water treatment system for easy maintenance combines SmartChlor Technology with FROG’s patented Minerals. The sanitizing minerals last 4 months and the SmartChlor Cartridge lasts up to 4 weeks. This automatic hot tub cleaning 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, this automatic mineral water system creates Fresh Mineral Water for continuous crystal clear water and peace of mind when it comes to hot tub care. With FROG @ease, you use less chlorine, making the water easier on skin, swimsuits and your hot tub’s surfaces. This swim spa accessory uses FROG Minerals to clean organic contaminants, condition the water for softness and absorb acid to help keep pH balanced. It 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. FROG Hot Tub Support Chemicals help balance water. Use FROG SooTHe to increase Total Hardness, FROG TArget to increase Total Alkalinity, FROG JumpH to raise pH and FROG DropH to lower pH or Total Alkalinity. FROG @ease does not contain cyanuric acid. The CDC recommends not using cyanuric acid or chlorine products with cyanuric acid in hot tubs/spas.
