The Spa Frog @Ease Mineral Cartridge is a disinfectant that contains a patented mineral formula that destroys bacteria while neutralizing acids, which helps keep the pH in a acceptable range with less monitoring.
Replace the Frog Mineral cartridge after four months, after using a total of four Smartchlor cartridges, or when draining and refilling the hot tub with fresh water.
