Water Chemistry

As with any pool, it is important that you maintain proper water chemistry of the pool water, including pH, 

alkaline content, and calcium levels. The only special requirement for SPS is to maintain proper levels of 

salt and stabilizer. It is important to maintain these levels in order to prevent corrosion or scaling and to 

ensure maximum enjoyment of the pool. Test your water periodically. It is recommended that pool water 

be professionally tested a minimum of twice per season. Your local pool store can provide you with the 

chemicals and procedures to adjust the water chemistry. Be sure to tell the pool store that you are using a 

salt chlorine generator.

Saturation Index

The saturation index (Si) relates to the calcium and alkalinity in the water and is an indicator of the pool 

water  “balance”. Your  water  is  properly  balanced  if  the  Si  is  0  ±.2.If  the  Si  is  below  -0.2,  the  water  is 

corrosive and plaster pool walls will be dissolved into the water. If the Si is above +0.2, scaling and staining 

will occur. Use the chart below to determine the saturation index.

Si = pH + Ti + Ci + Ai - 12.1
