Fresh Water Mineral Spa Sanitizer

This Freshwater mineral spa sanitizer introduces silver ions into the spa water, inhibiting bacterial growth. It is designed to suspend inside of the filter standpipe on Hot Spring spas beginning in 1990, Tiger River spas beginning in 1992, all Limelight spa models, and Hot Spot and all Solana spa models beginning in 1998. This continuous silver ionizer cartridge will charge the water one time and that “charged” water will last for four months. Two-year shelf life when kept in a dry place.
