Nature2 Mineral Stick uses patented mineral-bed technology to destroy bacteria. 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 (Spa Shock), the most recommended spa oxidant, Nature2 Spa becomes a complete spa sanitizing system (use SpaBoss Chlor Aid to maintain minimum chlorine levels of 3ppm). And managing your spa is easier than ever; Nature2 Spa slips into your spa filter and lasts up to four months.
Note: Nature2 is not a registered sanitizer. Minimum chlorine levels still need to be maintained.
