Make spa maintenance effortless with the FROG Serene Bromine Cartridge, crafted for both FROG Serene Floating and In-Line Systems. This easy-to-replace cartridge ensures consistent, effective sanitization while working with FROG Sanitizing Minerals to keep your hot tub water crystal clear and luxuriously soft.
Bromine offers a gentler, low-odor alternative to chlorine, dissolving slowly for steady sanitization and less pH fluctuation. Each adjustable cartridge lasts 2–4 weeks, helping reduce bromine use by up to 50% — saving time, money, and maintenance effort.
Enjoy sparkling clean, smooth-feeling water in any spa — no special equipment required. With FROG Serene, you can spend less time balancing chemicals and more time unwinding in comfort.
