What should you do if the pH of an indoor health club pool is reading 7.6?

Add Muriatic Acid
Add Sodium Bicarbonate
Add Sodium Carbonate
Increase pool temperature

The correct answer is: Add Muriatic Acid

If the pH of an indoor health club pool is reading 7.6, this means that the water is slightly basic. In order to balance the pH, an acid is needed. Adding Muriatic Acid, also known as hydrochloric acid, will lower the pH level towards neutrality. The other options, Sodium Bicarbonate and Sodium Carbonate, are bases and will only increase the pH level. Increasing the pool temperature will not have any effect on the pH level. Therefore, the correct course of action is to add Muriatic Acid to balance the pH level.
