POOL FROG is a hassle-free pool care system that doesn’t just kill bacteria but kills bacteria two ways – with FROG minerals and a small amount of chlorine. The result is Fresh Mineral Water^® that is crystal clear and silky soft. There’s no daily dosing required, no heavy chlorine odors, and you get weeks of consistent, effective water care. You’ll never have to handle or measure pool chemicals, because everything you need comes in pre-filled cartridges.
