## Questions & Answers

**Q: How long do the mineral and bromine cartridges last?**
A: The blue mineral cartridge lasts 4 months or whenever you drain your hot tub. Each yellow bromine cartridge lasts 2 to 4 weeks depending on the size of your hot tub and how often it is used.

**Q: What are the benefits of using bromine instead of chlorine to sanitize my hot tub?**
A: Bromine can be an excellent alternative to chlorine for hot tubs – it is gentler on your skin, eyes and respiratory system which makes it a better option for users with sensitive skin or allergies. It also has a milder odor compared to chlorine.

**Q: How is FROG Serene different from traditional sanitizing methods?**
A: If you are tired of chlorine odors and measuring chemicals, FROG Serene is for you. FROG Serene is not just bromine – it uses minerals to create Fresh Mineral Water in your hot tub. Prefilled cartridges eliminate guessing and handling of chemicals.

**Q: What is Fresh Mineral Water?**
A: FROG’s Sanitizing Minerals and a low level of bromine make cleaner, clearer, softer water that's easier to take care of. It's sanitized water without the harshness of other products and with prefilled cartridges it's much easier too.

**Q: What's included in the box?**
A: 1 FROG Serene Mineral Cartridge and 4 FROG Serene Bromine Cartridges
