Use the "acid demand" solutions in your test kit to determine how much acid is needed to bring the pH down to 7. There should be a chart in the test kit that shows how much acid to add depending on the gallonage of the pool. It may take several weeks of this to bring the total alkalinity into desired ranges. Lowering the pH more than that may strip copper off the heat exchanger in the heater. Typically you will knock 10 points or so off the TA reading every time you do this.

Does chlorine affect alkalinity?
Chlorine will indeed affect alkalinity. It will lower the alkalinity. If you add chlorine gas to water, it will create hypochlorous acid and hydrochloric acid. Cl2 + H2O <-> HCl + HOCl Sodium Hypochlorite (Bleach) will do the opposite and raise pH.
Is muriatic acid alkaline based?
Yep, muriatic acid, or Hydrochloric was in high demand in the Industrial Age for its alkalinity
Why add hydrochloric acid to swimming pool?
Reduces alkalinity of swimming pool water (softens hard water)
What is a megaloblastic anemia resulting in a decrease of hydrochloric acid?
Pernicious anemia
Is a megaloblastic anemia resulting in a decrease of hydrochloric acid?
_ is caused by protozoan plasmodium
How do you raise the pH level in the pool?
there are two primary chemicals on the merket used to do this. 1.) soda ash usually packaged under the name pH rise or pH increaser. 2.)sodium bicarbonate usually packaged under the name alkalinity rise or alkalinity increaser. both of the above chemicals will increase both the pH and Alkalinity of the swimming pool water. always make sure your alkalinity is balanced before making any pH adjustment. it is also important to understand pH and alkalinity always move together and in the same direction. so a pH adjustment will cause a change in your alkalinity level the same way a alkalinity adjustment will cause a change in your pH. when you increase pH, alkalinity will also increase when you decrease pH, alkalinity will also decrease when you raise alkalinity, pH will also rise. always dose chemicals according to the directions on the chemical container and the volume of water you are treating.
What is the purpose of adding HCl in the chlorine water?
To decrease the pH of the pool, hopefully keeping it at whatever alkalinity/acidity you desire.
When zinc reacts with dilute hydrochloric acid does the temperature of the acid increase or decrease?
It increases.
If I increase alkalinity in my pool will that increase pH?
No. Alkalinity neutralize the acids. Based on how much you put in, will cause a reduction in your pH levels.
What do you measure hydrochloric acid in?
Hydrochloric acid can be measured in units of concentration, such as molarity (moles per liter) or normality (equivalent grams per liter). It can also be measured using pH, which indicates the acidity or alkalinity of a solution, or by titration with a suitable base to determine its concentration.
If my pool has too much alkalinity what should you do?
add acid
Will pH minus lower pool alkalinity it is very high 300 at the same time the PH is very low 7.0. what needs to be done?
Yes. Adding pH minus (Hydrochloric acid) will lower your alkalinity. You should get it down to the 100 range or so, and the aerate the water to raise the pH to acceptable levels again.
