What causes high ph in pool

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 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.

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.

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 pool shock increase 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.

What should be adjusted first alkalinity or pH?

Does chlorine lower pH?

Chlorine gas will lower your pH. … Both liquid chlorine (sodium hypochlorite) and powder chlorine (calcium hypochlorite) will raise the pH. Liquid chlorine will raise the pH more than powder chlorine. Either muriatic acid or sodium bisulfate can be used to neutralize these alkaline compounds.

Does high pH affect chlorine levels?

Chlorine level and pH level are the two most essential chemical balances in maintaining a pool. … pH affects chlorine levels when it is too high or too low. When the pH level is too low, chlorine is actually cleaning more thoroughly, but the pool water becomes corrosive.

What is a pH Decreaser?

$5.95. pH Decreaser for hot tubs reduces high pH and Total Alkalinity (TA) of spa water. Helps prevent harmful scale buildup on hot tub equipment, filters, and heater, caused by high pH.
