FROG Serene Hot Tub Starter Bundle – Floating System + Refill Kit (1 Mineral + 3 Bromine)

The complete FROG Serene setup for your hot tub — float it and forget it.

This bundle pairs the FROG Serene Floating Sanitizing System (for hot tubs up to 600 gallons) with a full Refill Kit, giving you roughly 4 months of soft, clean water right out of the box.

• 1× FROG Serene Floating Sanitizing System (01-14-3883)
• 1× Serene Cartridge Refill Kit – 1 Mineral + 3 Bromine Cartridges (01-14-3856)

FROG minerals fight bacteria and condition the water while the bromine cartridge sanitizes with up to 50% less chemical — gentler on skin, hair, and swimsuits. Snap in the cartridges, set the dial, and float it. That's the whole job.

Bundle and save vs. buying separately.
