Comfort, convenience and cost youll love! Youll get the comfort of water that wont turn eyes red or dry your skin. Its natural approach to chlorination eliminates the harsh chlorine odor associated with factory-produced chlorine. Convenience means no more mixing, measuring or carrying heavy buckets of harsh chlorine. Sanitizing pools happens automatically with salt chlorination by converting ordinary salt into chlorine now thats convenient! What if you could get the comfort and convenience you desire, but at a savings on chlorination costs of more than 50%? You can with Salt & Swim 3C! Salt & Swim 3Cs salt cell produces a ton of chlorine at half the cost of other forms of chlorine.
