Effortless hot tub care with prefixed mineral cartridges

FROG Serene Replacement Mineral Cartridges are designed for use in the FROG Serene Floating System, delivering a balanced approach to water care that pairs mineral technology with bromine for a clean, inviting soak. The cartridges arrive prefilled, so setup is fast and simple, helping you start your maintenance routine in minutes rather than hours.

Why choose FROG Serene Mineral Cartridges?

  • Prefilled cartridges offer ready-to-use mineral balance right out of the package.
  • Mineral technology works alongside FROG Serene Bromine to support clean water.
  • Each cartridge lasts about four months with typical use, reducing frequent replacements.
  • Cartridges are recyclable once they’ve reached the end of their life.
  • Designed to feel gentler on skin and swimsuits while protecting hot tub surfaces.
  • Backed by FROG’s 25+ years of water care expertise and patented Mineral Technology.

Real-life use, real-world benefits

  • Enjoy clear water with a smoother, softer feel for evening soaks after a long day.
  • Maintain a comfortable soak experience even if your water balance fluctuates between uses.
  • Save time with a straightforward, predictable maintenance routine thanks to the prefilled design.
  • Upgrade your hot tub care with a system that emphasizes convenience and consistency.

Notes on expectations: these mineral cartridges are designed to complement your existing sanitization routine. Results may vary based on tub size, usage frequency, and water chemistry. They are offered as a helpful option to support your maintenance goals, not a guaranteed outcome.
