FROG® Serene Mineral Cartridge – Spa Floating & In-Line (4 Months)
The FROG Serene Mineral Cartridge is a patented water care solution that combines silver and zinc minerals to naturally sanitize your spa water. Unlike traditional chemical-only treatments, this cartridge works continuously to destroy bacteria and control algae while conditioning the water for a softer, more comfortable soak. Compatible with FROG @ease® Floating Systems and FROG Serene In-Line Systems, it's the perfect choice for spa owners who want cleaner water with less effort.
Key benefits include:
- 4-month lifespan – Replace only 3 times per year
- 50% less chlorine needed compared to traditional methods
- Softer, silkier water that's gentle on skin and swimsuits
- No pH balancing required – minerals naturally stabilize water chemistry
- Easy installation – works with floating or in-line systems
