Maintaining proper water chemistry is vital for a safe and enjoyable spa experience. Regularly testing and balancing the water protects the equipment and ensures bather comfort. Key parameters include pH, alkalinity, and sanitizer levels. Consistent monitoring prevents scaling, corrosion, and bacterial growth.
Always follow the recommended ranges for each parameter, as outlined in this manual. Adjusting these levels requires specific chemicals, used carefully according to product instructions. Proper water balance extends the life of your spa and provides a clean, healthy environment for relaxation.
Testing Water Parameters
Regularly test your spa water – ideally 2-3 times per week, and after each use – using a reliable test kit or strips. Key parameters to measure include pH, total alkalinity, and sanitizer levels (chlorine or bromine). Accurate testing ensures the water is properly balanced, preventing corrosion, scaling, and ineffective sanitation.
Record your results to track trends and make informed adjustments. Pay close attention to the test kit’s instructions for accurate readings. Consider professional water testing periodically to confirm your results and identify any potential issues not detectable with standard kits.
Balancing pH Levels
Maintaining the correct pH level – ideally between 7.2 and 7.8 – is crucial for water comfort and equipment protection. Low pH (acidic water) can cause corrosion and irritation, while high pH (alkaline water) leads to scaling and cloudy water.
Use pH increaser (soda ash) to raise pH and pH decreaser (sodium bisulfate) to lower it. Always follow product instructions carefully, adding chemicals in small increments and retesting after each adjustment. Proper pH balance maximizes sanitizer effectiveness and ensures a pleasant spa experience.
Adjusting Alkalinity
Total alkalinity acts as a pH buffer, preventing drastic swings in pH levels. Ideal alkalinity ranges from 80 to 120 ppm. Low alkalinity causes pH instability, while high alkalinity makes pH difficult to adjust.

To increase alkalinity, use an alkalinity increaser (sodium bicarbonate). To decrease alkalinity, aeration or a muriatic acid solution (handle with extreme caution!) may be necessary. Adjust alkalinity before adjusting pH, as changes in alkalinity will affect pH readings. Consistent alkalinity ensures water balance and protects your spa’s components.
