The SPA FROG Mineral Cartridge contains a patented mineral formula that destroys bacteria while neutralizing acids, which helps keep the pH in a safe range with less monitoring.

This product must never be used alone but always supplemented with a source of bromine or chlorine. Replace the SPA FROG Mineral Cartridge after 4 months or when draining and refilling spa with fresh water.
