What happens if pH is too high in pool?
When the pH level in your pool exceeds 7.8 pH, your water is considered to have high pH. This means that your water is now too soft and there can be consequences. … In addition, high pH runs a risk with your chlorine, as your chlorine will no longer disinfect fully.
What causes low pH in pool?
In most cases, low pH levels are caused by natural factors like a heavy rainstorm, overuse, and improper use of chemicals. Natural rainwater has a pH of 5 – 5.5, so it is naturally acidic. A substantial amount of rainfall can alter the pH of pool water to become more acidic.
How does chlorine affect pH?
High chlorine levels decrease the pH of your pool’s water, making it more acidic. The more acidic the water, the higher the likelihood of corrosion. This corrosion can affect metal piping, equipment, and the surface of your pool (tiles, liners, concrete, etc.).
Does chlorine increase 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. … So the net effect on pH is zero (or almost zero).
Will Shocking pool lower pH?
Bromine, another sanitizing chemical, has a pH of 4.0. With continued use, both can reduce your pool pH. Shocking the pool will lower the pH, whether you use chlorine-based shock (calcium hypochlorite), or the non-chlorine kind (potassium peroxymonosulfate).
How do I fix high pH in my pool?
Use a pool test kit to check the pH, acid demand, and total alkalinity. Once you’ve determined that the pH level is too high, you should now work to restore the balance. There are two main products for lowering the pH. These are sodium bisulfate (also known as dry acid) and muriatic acid.
What do I add to my pool if the pH is low?
Most pool experts recommend a pool pH between 7.2 and 7.8. To raise or lower pH, a pool custodian simply adds acids or alkalis into the water. For example, adding sodium carbonate (soda ash) or sodium bicarbonate (baking soda) will generally raise the pH, and adding muriatic acid or sodium bisulfate will lower the pH.
Will low pH make my pool green?
Improper pH Balance
Green water is most often a sign of algae, not necessarily bacteria, but different pools have different bacteria that can affect the water. … If the pH level is too low, the water is acidic and over time, it will erode plastic and metal components.

Does chlorine lower pH in pool?
Chlorine gas will lower your pH. This can often be a very drastic effect, causing a very rapid drop in pH. If the pH is not maintained at the 7.2-7.8 range it can drop to very low levels (pH 2.0-4.0) in a matter of a few hours. This can cause injury to swimmers and damage to your pool.
Why is the pH in my pool always high?
An increase in the pH level can be caused by several things. A first cause is the addition of chlorine stabiliser or HTH Granular to the pool water. … A higher pH level can also be caused by a sudden rise in temperature of the water. However, much more important than the causes are the effects of such a high pH level.
Can I add chlorine and pH up at the same time?
Chemicals that affect the levels of pH and alkalinity need to be added to the swimming pool first. Getting the pH and total alkalinity sorted out will allow for the addition of further chemicals that affect the hardness and cleanliness of the water.
Should I add acid or chlorine first?
The addition of the chlorine or salt will give you the pH increase. It’s not worth it to add an alkali one day, to raise the alkalinity or the pH, then an acid the next when neither was necessary!
