Description

SPA AND HOT TUB USE: Each level teaspoon (0.17 oz.) of this product will provide approximately 1.4 ppm available chlorine in 500 gallons of water. Using an appropriate test kit, test and adjust the water to the following values: pH 7.2-7.8, total alkalinity 60-100 ppm, calcium hardness 200 ppm minimum. Maintain these conditions for proper spa and hot tub operation by frequent testing with a test kit. Do not allow cyanuric acid level to exceed 150 ppm. It is recommended that spas and hot tubs be drained every 30-90 days. More often under heavy use. Consult manufacturer’s recommendations concerning the compatibility of chlorine sanitizers with their equipment. Some oils, lotions, fragrances and cleaners may cause foaming or cloudy water and may react with chlorine sanitizers to reduce their efficacy. START-UP (FRESHLY FILLED): 1. Turn on the circulation system and ensure that it is working properly. 2. Add 6 teaspoons of this product for each 500 gallons of water. Check the free available chlorine (FAC) and, if below 4-5 ppm, repeat as needed. Re-entry into treated spas is prohibited above levels of 3 ppm of chlorine.

  • Works great
Size: 1-Pack
We bought a new house that included a hot tub and we went through multiple cleaning cycles and draining, including purging with Oh, Yuck! and doing a majorly strong chlorine clean, even though our long-term sanitizer is bromine. Between Oh, Yuck! and this chlorine, plus draining between cleaning types, we feel confident that the hot tub is safe to use. (We're a bit paranoid due to friends having contracted an illness from a resort hot tub.) Using this and test strips to measure PPM, I was able to get the chlorine levels right where we wanted them. ... show more
