This stick-like product conveniently fits inside your spa's filter cartridge, providing FROG mineral protection for spas up to 600 gallons. Supplement with a low level of chlorine or bromine and spa care is complete with soft water and a crystal clear shine.
How It Works
Filter FROG simply fits into the center of a spa filter cartridge. It is a one piece design that can be shortened if necessary. The water moves in and out of the louvered design, dispensing a low level of minerals into the spa. Simply supplement with 1 ppm of chlorine or bromine.
