Does chlorine shock raise pH?

Chlorine based pool shock (Calcium Hypochlorite) has a high pH, and will naturally raise the pH level of your swimming pool water, in addition to changing your chlorine level. Chlorine free shock has a neutral pH, and will not affect any of your pool chemical levels.Click to see full answer. Similarly one may ask, does chlorine affect pH? Using liquid chlorine raises the pH of the water. Liquid chlorine does not raise pH. When added to water, liquid chlorine (which has a pH of 13) makes HOCl (hypochlorous acid – the killing form of chlorine) and NaOH (sodium hydroxide), which raises pH.Subsequently, question is, is chlorine and shock the same thing? Shock is chlorine, in a high dose, meant to shock your pool and raise the chlorine level quickly. Chlorine tabs (placed in a chlorinator, floater, or skimmer basket) maintain a chlorine residual in the water. You do need to use both tabs and shock. Secondly, how much does shock raise chlorine? Raising the chlorine level by shocking the pool Calcium hypochlorite is the key ingredient in chlorine-based shock, so make sure this is what you purchase. To shock the pool, you typically need to raise the chlorine level in the pool at or above 10 ppm.Can you add shock and chlorine at the same time?Chlorine shock + Sequester Agent: Chlorine shock will also disrupt stain & scale chemicals, aka chelators or sequestering agents, if added at the same time. Add Stain & Scale chemicals a day before or several days after, shocking a pool.
