Nature2 Spa uses patented mineral bed technology to destroy bacteria in your spa. Its revolutionary process significantly improves the look, feel and smell of your spa water by dramatically reducing chlorine and bromine requirements. If used with MPS, the most recommended spa oxidant, Nature2 Spa becomes a complete spa sanitizing system - the only non chlorine spa sanitizing option available. And managing your spa is easier than ever; Nature2 Spa slips into your spa filter and lasts up to 4 months. It improves water quality, works with all spa flow rates, and leaves water softer and clearer.Improves water quality
