Zodiac Nature 2 Sanitizer for Spas & Hot Tubs

Nature2 Spa sanitizer uses patented mineral-bed technology to destroy bacteria. Its revolutionary process significantly improves the look, feel, and smell of 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. Managing your spa is easier than ever, Nature2 Spa slips into your spa filter and lasts up to four months.
