NEVER ADD WATER TO ACID; ALWAYS ADD THE ACID TO THE WATER. (If water is added to acid, a violent reaction may occur and splash concentrated acid back at you). Acid may not need to be stirred, but the solid chemicals should be stirred to speed up dissolving. The size of a swimming pool determines how much acid can be safely added to the water.

Add chlorine as needed to maintain the FRC at >10 mg/L. Because the biocidal effect of chlorine is reduced at a higher pH, adjust the pH to 7.5–8.0. The pH may be lowered by using any acid (e.g., muriatic acid or sulfuric acid used for maintenance of swimming pools) that is compatible with the treatment chemicals.

To lower pH, sodium bisulfate or muriatic acid can be used. Alkalinity 80–220 ppm. Most effective way of raising total alkalinity without great effect on pH is to add sodium bicarbonate (baking soda) Calcium is one of the most important minerals for pool operators to monitor. Calcium is usually 70% of the total hardness reading

Muriatic acid (also known as muratic acid), a common HCl stock solution found at most hardware and swimming pool supply stores, is diluted with water to prepare HCl field solutions. The dilution factor depends on the concentration of HCl stock solution. Currently available grades of muriatic acid contain about 32 percent HCl by weight.
