How do you lower alkalinity but not change pH in a swimming pool?

Initially, you can't. What you do to lower alkalinity is first lower the pH to under 7.2, but not lower than 6.9. Then you aerate the pool, by creating bubbles with your brush, or by running a water feature, if you have one. This will lower your alkalinity. Maintain this lower pH and aerating until you get your alkalinity where you want it. Then retest your pH. If it is now too low, you add Mule Team Borax, say a 1/4 a cup, and then retest. The borax will raise your pH without raising your alkalinity. See the poolforum.com for more help if needed.

What is the chemical ALK in a swimming pool?
Alkalinity
What will result if sodium bicarbonate is used to lower ph in a swimming pool?
Bicarbonate will RAISE the pH and total alkalinity.
Can you use sodium bisulfate to lower TA?
Sodium bisulfate (AKA sodium hydrogen sulfate or sodium acid sulfate) is an acid that will lower pH. If you lower the pH of a swimming pool buffered with baking soda (sodium bicarbonate) and maybe cyanuric acid (stabilizer), your alkalinity will go down, along with the pH. But usually, what people want is to lower the alkalinity (or TA) without lowering the pH. When you lower the pH on a carbonate buffered pool, you convert some of the carbonates into carbonic acid, where they no longer contribute to the measured alkalinity. But, as soon as you raise your pH, the carbonic acid switches back to carbonate, and your TA goes right back up with the pH. To actually LOWER the alkalinity, you have to lower the pH, and then REMOVE some of the carbonic acid, which you can do be aerating the pool, since carbonic acid is a form of carbon dioxide gas.
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.
How do you lower alkalinity and raise pH?
To lower the alkalinity in a pool you can use PH Minus or Muriatic acid. When adding pour into one spot in the deep end of the pool away from circulation, make sure the circulation system is running. Do not apply near metal fittings or near the pool skimmer. Also make sure you follow directions when using the product.ANS2Can't be done. It is like slowing down while you run faster. Lowering the alkalinity is the same as decreasing the pH. The less alkaline the water, the lower the pH.
How could HCI be used in a swimming pool?
To adjust pH and/or lower alkalinity.
If you have a good alkalinity with mains water what would lower it in a swimming pool with out the addition of chemicals.?
Add rain water this has very low alkalinity
How do you lower the alkilinity of a swimming pool?
You have to know what you are doing. The addition of muriatic acid lowers the pH and total alkalinity in swimming pools.
What is the chemical ALK in a swimming pool?
Alkalinity
What will result if sodium bicarbonate is used to lower ph in a swimming pool?
Bicarbonate will RAISE the pH and total alkalinity.
Is alkalinity dangerous for humans in swimming pools?
Alkalinity is not an actual "chemical", however if you are concerned about increasing the alkalinity in your swimming pool, you are perfectly safe. The chemical that increases "total alkalinity" in a swimming pool, is only baking soda. It wil not harm the human body!
Why add hydrochloric acid to swimming pool?
Reduces alkalinity of swimming pool water (softens hard water)
Will adding a flocculant to the pool water lower the Total Alkalinity?
No
What household item can be used to lower pool Alkalinity?
baking soda
What causes Bumps jthat are forming on swimming pool surface?
pH and total alkalinity out of balance.
What does raising the alkalinity and pH do for a pool?
Alkalinity readings for your pool is quite essential. When you increase your alkalinity, that makes it so your pH is more resistant to change due to weather, leaves etc
Why is sodium bisulfate used in a pool?
It is used to lower both ph and alkalinity.
