Spa Frog for Filter Core
The original Spa Frog in-filter mineral system is an effective way to care for hot tub water that reduces chlorine or bromine use. In fact, with minerals doing the bulk of the job, you can use up to 50% less than standard spa water treatments. With just a low 1.0 ppm of bromine or chlorine, your spa care is complete without fading swimsuits or harsh odors. Spa Frog works great with ozonators too!
The unit fits inside your filter. It draws water in through the openings in the cap and the scooped slats at the top, and circulates it through our mineral formula for greatest effectiveness. Water is then released through the bottom openings.
Lasts 4 months, with an easy reminder dial to help you remember when to replace it.
