Test the water for pH, Alkalinity, Calcium Hardness and Temperature, then follow the simple steps below:

1.  Write your pool’s pH level here: 

 pH: 

________

2.  Find your Alkalinity level in the chart below, and write the

corresponding Alkalinity Factor here: 

Alkalinity Factor: ________

5.  Add the results from steps 1 through 4 above and write the result here: 

        Total of above: ________

        - 12.2

6.  Subtract 12.2 from step 5 and write the result here: 

Saturation Index = 

____

If the Saturation Index above is between –0.3 and +0.3, the water is well balanced.

If the Index is more than 0.3, the water will tend to cause scaling or get cloudy. Alkalinity and pH

should be reduced accordingly, but maintained within recommended levels.

If the Index is less than -0.3, the water will tend to be aggressive toward the pool surface, equipment

and bathers. Alkalinity and pH should be increased accordingly, but maintained within recommended levels.
