How It Works
The FILTER FROG® mineral sanitizer fits easily into the center of your spas filter cartridge. It is a one-piece design that can be shortened if necessary. The unique design draws in your spa water through the openings in the cap and sides and circulates it through our patented mineral formula dispensing a low level of minerals into the spa. Simply supplement with 1 ppm of chlorine or bromine.
