Frequently Asked Questions

The blue Mineral Cartridge lasts 4 months or whenever you drain your hot tub. The yellow Bromine Cartridge lasts 2 to 4 weeks depending on the size of your hot tub and how often it is used.

Unlike chlorine, bromine slowly dissolves in hot water so it’s easier to regulate with far less odors. Bromine is less impacted by pH swings than chlorine, ensuring water is well sanitized even if it’s not perfectly balanced.

FROG Serene uses FROG Sanitizing Minerals and low levels of bromine to create Fresh Mineral Water∞ in your hot tub. Prefilled cartridges eliminate guessing and handling of chemicals.

Fresh Mineral Water∞ is our signature water quality experience — clean, clear and silky-soft water made possible by our patented mineral technology combined with significantly lower levels of bromine. The result is water that’s gentler on skin and free from the harsh feel and strong odors of traditional hot tub care.
