Review: Great for blow up spa - This product works great
Review: Good bargain for a product that works well. - The Frog Spa mineral cartridge system makes taking care of my hot tub so much easier. This the third cartridge I have ordered through desertcart and have never been disappointed. Although I use chlorine in my spa and this cartridge says it's for a bromine system I verified with my spa dealer that the chemicals are the same for both systems. This cartridge is almost $10 less expensive than the darker colored one that says it's for a chlorine system. My spa water stays clear and doesn't have any strong chemical odor for 3 to 4 months with monthly chlorine cartridge changes.

## Questions & Answers

**Q: How long do the mineral cartridges last?**
A: The blue mineral cartridge lasts 4 months or when draining the hot tub.

**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
