This SPA FROG offers another approach to mineral spa care that fits in your filter. The unique design draws water in through the openings in the cap and the scooped louvers at the top and circulates it th with an easy reminder dial to help you remember when to replace it.  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 you 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 louvers at the top and circulates it through our mineral formula for greatest effectiveness. Water is then released through the bottom openings. Simply supplement with a low level of bromine or chlorine and shock regularly with OxySpa non-chlorine shock. Lasts 4 months with an easy reminder dial to help you remember when to replace it. Compatible with bromine and chlorine.
