What happens if pH is too low in pool?

Too low a pH has a significant influence on the effect of the chlorine. If the pH level is too low, you will have to add a large amount of chlorine to ensure proper disinfection of the water. If the pH level becomes too low, it may also cause the water to turn brown to black, which is not attractive to swim in!

How long does it take to raise pH in pool?

So, instead of one level out of balance, you now have two. You should test both pH and alkalinity again within 24 hours after attempting to raise the pH.

A rule of thumb is 1.5 lbs. of baking soda per 10,000 gallons of water will raise alkalinity by about 10 ppm. If your pool's pH tested below 7.2, add 3-4 pounds of baking soda.

Does chlorine raise pH?

7. 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.
