The FROG Leap Mineral system utilizes a patented combination of sanitizing minerals along with a LOW level of chlorine for a complete water care system. All components are introduced into the water via a housing known as the Infuzer that is installed after the pump and filter. The Anti-Bac Mineral Pac is inserted first, helping to destroy bacteria all summer!, while the Torpedo Pac goes in next, precisely metering the right level of chlorine for each pool.
