Using an effective sanitizer to control and prevent bacteria growth is the most important start-up procedure in our program. Maintaining the proper sanitizer level will ensure the spa water remains clean and fresh.
The effectiveness of chlorine depends heavily on the pH level of the spa water. In order to get the most effective and economical benefit of chlorine, a pH range of 7.2 to 7.8 should be maintained.
- To begin, test and balance your spa for Total Alkalinity (TA), Calcium Hardness (CH), and pH.
- Add 1.2 oz. of Spa Selections™ Chlorinating Granules for every 500 gallons of water while the water is circulating.
- Wait 10 minutes and test the water with an at-home test kit to ensure the spa’s pH and alkalinity levels are within proper ranges. Your spa water should have a pH between 7.2 – 7.8, a total alkalinity between 80 – 120 ppm, a calcium hardness level between 150 – 400 ppm and the sanitizer level should read between 3 – 5 ppm.
- Once the water is balanced and sanitized, the last step is to shock-oxidize the spa water. During normal use, body oils, lotions and other organic contaminants can enter the water. When these build up, the water can become cloudy. To destroy these impurities, it is critical to shock-oxidize your spa water. This can be accomplished by using Spa Selections™ Non-Chlorine Shock Oxidizer. Be sure to shock-oxidize your water on a routine basis, preferably after each use and no less than once a week. Regular shock oxidation will rid your spa of residual soaps, oils and other organic materials that can collect from normal use. To shock-oxidize the water, keep the jets running and add Spa Selections™ Non-Chlorine Shock Oxidizer for oxidizing according to the directions on the label.
Sanitizing with bromine has become increasingly popular. Unlike chlorine, when bromine combines with bather waste and other contaminants in the water, it remains a very effective sanitizer. Bromine is also far less pH-dependent than chlorine. Spa Selections™ Bromine Tablets are added to a suitable feeder that will gradually release the bromine and maintains a constant level of bromine in the water. When using Spa Selections™ Bromine Tablets, you will also need to use Spa Selections™ Brom-Start when first filling your spa, and then each time you drain and refill your spa to ensure a fully bromine-based sanitizer system
- To begin, test and balance your spa water for Total Alkalinity (TA), Calcium Hardness (CH), and pH with a reliable at-home test kit to ensure the spa's pH and alkalinity levels are within proper ranges. The pH should be between 7.2 - 7.8, the alkalinity should read between 80 - 120 ppm, the calcium hardness should range from 150 - 400 ppm.
- Next, add half an ounce of Spa Selections™ Brom-Start for every 100 gallons of water to establish an initial bromide reserve in the water.
- Add the Spa Selections™ Bromine Tablets to the Spa Selections™ bromine tablet floater, or other suitable floater adjusted to the manufacturer's directions. Place the floater in the spa and allow the water to circulate at least 15 minutes, then test the bromine level with a reliable test kit to ensure it is in the range of 2 - 4 ppm. If not, adjust the floater as needed, allow the water to recirculate another 15 minutes and retest.
