Boost 1lb (1)

Works in the hot tub

I use this product with EZ Spa OM. It is like the shock treatment you would use when using other products. I have a hot tub we use every weekend which is out of town. I treat it with the EZ Spa OM and Boost once a week. Spa always is clear and in excellent condition (other than the sand we track in it). I have been using this product with EZ Spa OM for about 5 years and absolutely love it. I would never go back to chlorine or bromine.
