Caution:
Do not use your spa until the pH level of the water is between 7.2 and 7.6. A pH level below 7.2 or above 7.6
may damage the spa shell and power pack, and void your warranty.
All water is either acidic, alkaline, or neutral. pH is defined as a method of measuring this characteristic. A
pH level of 7.0 would be neutral. A pH level above 7.0 would be alkaline while a pH level below 7.0 would
be acidic. The pH level of your spa water must be kept between 7.2 and 7.6. Above 7.6 the water will
become discolored and cloudy. pH levels below 7.2 will cause corrosion to metals in the circulation system.
Both high and low pH levels will cause eye irritation. Improper pH levels also reduce the effectiveness of
disinfectants.
Maintain an ideal pH level as follows:
1. Test the pH level of the water regularly with a reliable test kit.
2. Adjust the pH level as required.
- Increase pH by adding soda ash.
- Decrease pH by adding sodium bisulfate.
3. Refer to the table below and determine the dosage level per 100 gallons.
4. Add chemicals to at least one gallon of water.
5. Pour the mixture into the spa with circulation system on.
6. Wait at least 3 hours. Recheck the pH level.
High pH - Add Sodium Bisulfate (pH down)
