When ordering the product, we provide a detailed instruction pamphlet regarding the initial startup, utilization of a sanitizer, operation, and the benefits of H2OFix. Please Note that if you follow the included product instructions, using a sanitizer, such as chlorine, will be reduced.
However, the amount of sanitizer and/or use of it is subject to the cleanliness and use of the hot tub, jacuzzi, or jetted tub and how it is maintained. For example, frequent usage can introduce contaminants like soap, dirt, and body oils into your system, requiring additional maintenance and possibly a need to use sanitizer.
