Just dial in your desired bromine level based on your spa's needs, snap the cartridge into place, and enjoy weeks of crystal-clear water. For optimal performance, replace your Mineral Cartridge every 4 months and the Bromine Cartridge every 2-4 weeks.

You and your family deserve the best spa care possible, and the Frog Spa Bromine Cartridge delivers just that - clean, comfortable water without the complexity of traditional sanitizing methods.
