Proclear-Mineral Sanitizer are specially designed to fit Jacuzzi Filters (screw into the top of the filter).
Just like Nature2 Spa, Proclear 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 Non Chlorine Sanitizer, the most recommended spa oxidant, Proclear becomes a complete spa sanitizing system - the only non-chlorine spa sanitizing option available. And managing your spa is easier than ever; Proclear screws into your spa filter and lasts up to four months.
