The removal of this dissolved CO2 from the water will have a direct impact on the total alkalinity, and will cause its value to fall.
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.

It’s best to shock a pool with a low pH range of 7.2-7.4. Alkalinity is closely related to pH, and when it’s too high, it can prevent you from lowering your pH easily, and it can easily throw off bicarbonates, which make the pool cloudy.

Typically goes hand in hand with pH. If the alkalinity reading is low, then most likely the pH reading is low and visa versa. Typically chlorine shock contains alkaline which will help raise the alkaline level. On the flip side of that, chlorine tablets which contain cyanuric acid tends to lower the alkalinity.
Can I add pH up and alkalinity at the same time?
Pool pH and Alkalinity are both Low
To raise pH and Alkalinity at the same time, start with Alkalinity, and add enough Increaser to raise Alkalinity to 100 ppm. Add 1 lb Alkalinity Increaser per 10,000 gals, to raise Alkalinity 10 ppm. The pool pH level may rise and follow, without added pH Increaser.
Can I add chlorine and alkalinity at the same time?
Chemicals that affect the levels of pH and alkalinity need to be added to the swimming pool first. Getting the pH and total alkalinity sorted out will allow for the addition of further chemicals that affect the hardness and cleanliness of the water.
