Caldera Spas FROG @ease Mineral Cartridge

The Caldera Spas FROG @ease Bromine Cartridge is designed for use in both floating and in-line FROG spa systems. It delivers consistent, low-level bromine sanitation for softer, crystal-clear water with less chemical odor and irritation. Each pre-filled cartridge helps cut maintenance time, reduces bromine usage, and typically lasts 3-5 weeks depending on spa size and usage. Replace the cartridge regularly to keep water safe, fresh, and easy to maintain.
