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.
liquid muriatic acid
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.
Muriatic acid
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.
A small of amount of muriatic acid
pH refers to the level of acidity or alkalinity. less than 7 is acidic, more than 7 is alkaline. if you want to lower your alkalinity, add muriatic acid. It will lower the pH though
1-2 gallons of muriatic acid will break down the buffer solution(alkalinity in the water). Will then probably have to raise pH back up
You have to know what you are doing. The addition of muriatic acid lowers the pH and total alkalinity in swimming pools.
Use muriatic acid to lower your pH. Be mindful of your alkalinity also as the muriatic acid will lower it too. You need both (actually everything in balance) pH 7.2-7.8 Alk 80-120
I tried both types of acid. The pH Minus (dry acid) and then the muriatic acid. I did not have much luck at all with the total alkalinity (TA) dropping with the dry acid. When I used the muriatic acid the TA dropped within a couple of days. So to answer your question I'd have to say the muriatic acid. It is much cheaper ($12 a case) at Leslie's Pool Supply and probably cheaper other places. The muriatic acid was also quicker and had better results.
No, conditioner is added to water to help mantain chlorine. Muriatic acid is used to lower pH or alkalinity.
There are 3 principal chemicals for lowering pH: muriatic acid, sodium bisulfate (dry acid) & CO2. If this is a commercial application then CO2 may be a viable source. The sodium bisulfate is dry acid which when mixed with water makes liquid acid but does not have the odor. Muriatic acid and sodium bisulfate both lower total alkalinity at hte same time as lowering the pH. CO2 may raise total alkalinity at the same time as lowering pH. The total alkalinity is important to have a stable pH which in turn is important to have a relatively constant pH for the proper effectiveness of the sanitizer (chlorine) Any other questions feel free to email me direct.

1 ppm HCl in aqueous solution would have a pH of around 6.

Promotes rust and eats into some non ferrous metals However you cant get out of using it if you have a pool and it is nothing to be concerned about as the concentration in pool water is extremely low
Muriatic acid will not lower the Harness(calcium chloride)level in a swimming pool. Dilution is the only effective method to lower the calcium hardness level. Muriatic acid is used to lower the pH and total alkalinity of pool water.
