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):
- Turn on the circulation system and ensure that it is operating properly.
- 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 if needed. Re-entry into treated spas is prohibited above levels of 3 ppm of chlorine.
Regular Use:
Turn on the circulation system and ensure that it is operating properly. Scatter approximately 3 teaspoons for each 500 gallons of this product over the surface of the water. Always use a clean dry spoon. Test for FAC and add additional product, if necessary, to attain 4-5 ppm FAC. Maintain 1-3 ppm FAC while the spa or hot tub is in use. After each use, shock treat with 9 teaspoons per 500 gallons of water to control odors and algae. Repeat as needed. Re-entry into treated spas is prohibited above levels of 3 ppm of chlorine.
