Testimonial – My Hot Tub Almost Maintains Itself

I am quite amazed. With BZT® Pool & Spa Treatment, the water is clear, tub rings are non-existent and the flow switch never shuts the heater off because the filters stay clean. The filters have even whitened up again. There is never any foam accumulation and the pH is very stable. Best of all, it just keeps running stable without frequent attention.
