100% bromine sanitizer in an easy-to-use liquid form. Add when the spa or hot tub is filled and weekly thereafter to maintain a bank of bromine in the water. Compatible with bromine sanitizing systems.
I have a 5 x 7 spa and for the 4 years I have had it I have only used this Reserve/Renew method. Water is clear and easy to maintain. I clean the filter weekly, often add aroma therapy oil designed for spas and when I do change the water use Metal Gone and other Leisure Time products.
