FROG® Serene Floating System – Mineral & Bromine Hot Tub Sanitizer – part #01‑14‑3883

Q: What’s included with the system?

A: One floating holder, one prefilled mineral cartridge, and one bromine cartridge.

Q: How long does each cartridge last?

A: Mineral lasts 4 months; bromine lasts 2–4 weeks, depending on use.

Q: Is it safe for sensitive skin?

A: Yes! The mineral system allows for lower bromine levels, making it gentler on skin, eyes, and spa surfaces.

Q: Do I need to add anything else to the water?

A: You may still need to balance pH and alkalinity, but daily chlorine/bromine dosing is unnecessary.

Q: Can I use this in any hot tub?

A: It’s ideal for hot tubs up to 600 gallons that do not have an inline FROG system built in.

Snap the mineral cartridge into one side of the floating holder.

Snap the bromine cartridge into the other side.

Turn the dial on the bromine cartridge to the recommended setting.

Place the floater in your spa and let it circulate.

Replace bromine cartridge every 2–4 weeks; replace mineral cartridge every 4 months.
