How to lower pool alkalinity level

How do I lower the alkalinity in my pool?

To lower pH and total alkalinity, use a strong acid such as muriatic acid, sulfuric acid, or sodium bisulfate, all of which lower both pH and TA, but at different rates. You need to use an accurate water test kit that can give you correct readings.

How do you lower alkalinity without lowering pH?

If you wish to lower the pH without also reducing the Total Alkalinity, simply pour the dose of muriatic acid about the pool. “ This would all be wonderful if it was only accurate. Still, just like the mythological “Chlorine Lock,” folkloric tales within the swimming pool industry do persist.

Does chlorine lower alkalinity?

Non-stabilized chlorines, like liquid chlorine (bleach) or cal hypo, each have a high pH. So you can have lower alkalinity, like 80-100 ppm, or even lower than 80 ppm if your LSI allows for it. Salt chlorine pools will often struggle with scale buildup that flakes off the salt cell and blows into the pool.

What should be adjusted first alkalinity or pH?

You should test alkalinity first because it will buffer pH. Your reading should be in the range of 80 to 120 parts per million (ppm). If you need to increase the alkalinity, add an increaser. To lower it, you’ll add a sodium bisulfate.
