Spa Frog Replacement Mineral Cartridge 01-14-3812

FROG Serene keeps your hot tub clean while eliminating the work and the guesswork. Instead of spooning in bromine daily, you simply replace a pre-filled cartridge about once a month. FROG Serene works by killing bacteria in two ways with sanitizing minerals and a very low level of bromine.

Features:

• Lower your bromine use up to 50%* with FROG minerals
• Soft feeling water that’s easier on skin, swimsuits and spa surfaces
