Starting and Maintaining Sanitizer levels
Sanitizing your spa with chlorine or bromine is very similar. Each sanitizer has its advantages and disadvantages.
Bromine: Whereas chlorine can sometimes cause offensive odors and skin irritation, bromine is less likely to
do so. Additionally, 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. Always
remember that bromine by itself is not a sanitizer, and it needs to be activated by shock in order to be
effective.
Chlorine: The most commonly recognized sanitizer is chlorine. However, 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,
you must maintain a consistent pH level of between 7.2 to 7.6. A disadvantage of using chlorine is that when
chlorine combines with bather waste and other contaminants in the water, not only does it lose its sanitizing
ability, it can cause odors and irritate eyes and skin.
After you choose a sanitizer, you will need to establish a baseline and maintain it regularly.
Starting with fresh water:
1. Establish a baseline by adding either granulated chlorine or bromine.
• Use half an ounce of chlorine for every 500 gallons of water.
• Use half an ounce of bromine for every 100 gallons of water.
2. Run the jets for 10 minutes.
3. Test the water. Make sure the pH, TA, and CH levels all fall within the ranges shown on the previous page.
Make adjustments where they are needed.
4. At this point, if you use bromine, it is not yet activated and it will not sanitize the water. You need to shock-
oxidize the spa water. Depending on the size of your spa, add one to two ounces of shock. You can use any
kind of shock you want.
5. Test the water again. When the water is balanced, your spa is ready to use.
Note: If you choose to use bromine, we do not recommend using a floater. You have more control over the
bromine level by adding bromine as needed. For more discussion on this, see page 37, “Common Water
Chemistry Questions”.
