Default Chlorine generator creates byproduct NaOH and raises pH and alkalinity

The chlorine generator in a saltwater pool uses electrolysis to disassociate salt NaCl into chlorine gas and sodium hypochlorie for disinfecting the pool water. The second part of the reaction produces NaOH which is a strong alkaline compound which raises the pH and total Alkalinity whenever the Chlorine generator is working.
