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: ________
		Pool Alkalinity		5			25			50			75			100		150		200			300			400
		Factor		0.7			1.4			1.7			1.9			2.0		2.2		2.3			2.5			2.6
3.	Find your Calcium level in the chart below, and write the
corresponding Calcium Factor here:																												Calcium Factor: ________
		Pool Calcium			5			25			50			75		100		150			200			300			400
		(CaCO3)
		Factor			0.3			1.0			1.3			1.5		1.6		1.8			1.9			2.1			2.2
4.	Find your pool temperature in the chart below, and write the
corresponding Temperature Factor here:																									Temperature Factor: ________
		Pool Temp	32			37			46			53			60		66		76			84			94			105
		Factor	0.0			0.1			0.2			0.3			0.4		0.5		0.6			0.7			0.8			0.9

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

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

- 12.2

____

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.
