The Spa Frog Serene Mineral Cartridge (0710#) is designed to work with the Spa Frog Serene bromine floating system. This mineral cartridge helps condition spa water, reduce bromine usage, and improve overall water quality. By releasing natural minerals into the water, it enhances clarity, reduces odors, and creates a more comfortable soaking experience.

Minerals help maintain cleaner water by inhibiting bacteria growth and supporting your primary sanitizer. With consistent performance lasting up to four weeks, this cartridge makes spa care easier and more enjoyable.
