king tech spa frog serene floating sanitizing system 01 14 3883

Make spa care effortless with the FROG Serene Floating System, the all-in-one solution that keeps your hot tub clean, clear, and luxuriously comfortable — without the hassle of daily chemical dosing. This innovative system combines FROG Sanitizing Minerals with a low level of bromine to create Fresh Mineral Water®, giving you softer-feeling water that’s easy on your skin, swimsuits, and spa surfaces.

The pre-filled, snap-in Mineral and Bromine Cartridges work together to kill bacteria in two ways while reducing bromine use by up to 50%. Simply let the system float in your spa — no measuring, no mess, and no guesswork. When the Bromine Cartridge runs low (every 2–4 weeks) or the Mineral Cartridge reaches 4 months, just replace and relax.

Each system includes everything you need for weeks of worry-free spa enjoyment:
✔️ Reusable Floating Holder
✔️ 1 Mineral Cartridge (lasts 4 months)
✔️ 1 Bromine Cartridge (lasts 2–4 weeks)
✔️ FROG Jump Start® Shock Packet
✔️ FROG Test Strips

With FROG Serene, maintaining your hot tub has never been easier — simply float, replace, and enjoy crystal clear, silky soft water every soak.
