The amount of acid required by your pool water to achieve the proper pH level.
Acid required to destroy excessive amounts of alkalinity.
The amount of acid needed to bring high pH and total alkalinity down to the proper levels as determined by acid demand test.
the amount of acid (or pH decreaser) water needs to reach the proper pH range. For example, to lower pH from 8.0 to 7.6, your pool may "demand" 2 quarts of acid. The actual amount needed will be dependent upon pool volume and other factors. Some test kits contain the titration test used to determine acid demand.
titration test used to determine proper amounts of acid (or pH decreaser) to reach correct levels. For example, to lower pH from 8.0 to 7.6, your pool may "demand" 2 qts of acid.
A measurement of the amount of acid that is needed to lower the pH and Total Alkalinity of your pool.
The amount of acid required to lower the pH and total alkalinity of pool water to the correct level.
