Hot Tub Opening Kit – FROG Serene Bromine System + Refill Kit, Test Strips & Shock

The complete bromine-based hot tub opening kit. FROG Serene combines bromine with FROG minerals for soft, clear water and a gentler feel than chlorine — ideal if you or your family are sensitive to chlorine's smell and sting.

• FROG Serene Floating Sanitizing System — for hot tubs up to 600 gallons
• Serene Cartridge Refill Kit (01-14-3856) — 1 mineral + 3 bromine cartridges, months of coverage
• FROG Test Strips, 50 count (01-14-3318) — reads chlorine/bromine, pH and alkalinity
• Jump Start Spa Shock — the start-up dose for a fresh fill

Mineral cartridges last about four months; bromine cartridges run 2–4 weeks each depending on tub size and use. Fill, shock, float, and test — that's the routine.
