The Spa Frog Serene Bromine Floating System Starter Kit (255#) provides a simple, effective way to keep spa water clean, clear, and comfortable. This 2‑part floating system uses a combination of bromine and minerals to deliver consistent sanitation while reducing chemical use and improving water feel.

The mineral cartridge helps condition the water and reduce bromine demand, while the bromine cartridge maintains a steady sanitizer level. Together, they create a self‑regulating system that minimizes daily maintenance, reduces odors, and keeps water silky and inviting.

Perfect for spa owners who want dependable sanitation without constant measuring or complicated routines.
