lower it
add some form of alkalinity booster for sure. bring it too about 110ppm, chlorine has a naturally high pH, but the higher alkalinity addition will stop acidic compounds from attacking the pH any further. depending on how low the pH is though you may have to add a pH booster, take your water into a pool shop for an in depth water analysis.
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.

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
To lower alkalinity without affecting pH levels in a swimming pool, you can use muriatic acid or sulfuric acid. These chemicals will reduce alkalinity without impacting the pH significantly. Be sure to follow the manufacturer's instructions and test the water regularly to maintain proper balance.
A small of amount of muriatic acid
No
To lower alkalinity in well water, you can try installing an acid injection system to neutralize the alkalinity. Another option is to use a water softener with an acid regeneration option to reduce alkalinity levels. It's advisable to consult with a water treatment professional to determine the best solution for your specific well water.
Add rain water this has very low alkalinity
baking soda
It is used to lower both ph and alkalinity.
To adjust pH and/or lower alkalinity.
