How do I raise the alkalinity in my hot tub without pH?
Add 1 tablespoon of baking soda to the hot tub for every 100 gallons of water it holds. For example, add 4 tablespoons of baking soda to a hot tub that holds 400 gallons of water. Turn on the hot tub jets and allow the water to circulate the baking soda for two to four hours.
How do you raise alkalinity without pH?

What causes low alkalinity in hot tub?
Why You Have Low Alkalinity First, it can be caused by humans. Rain water is a common offender in lowering the alkalinity of water, as it leans on the acidic side of the pH scale. If you don’t use a hot tub cover, you may find your water out of balance after a downpour. Chlorine could also be the culprit.

For low pH chlorines like Trichlor, 100-120 ppm might be a better range for you.
Can you use soda ash to raise alkalinity?
Follow the directions on the test kit you have for ascertaining the pH and total alkalinity. The optimum level for alkalinity is 80 to 150 parts per million. The optimum level for pH is 7.0 to 7.6. Soda ash will raise alkalinity but it will also raise pH, so it should only be used if both test low.
How do you balance pH and alkalinity in a hot tub?
If your PH and/or Alkalinity is high, you need to add a PH Minus to reduce these levels. Do this gradually. Add the correct dose of PH Reducer, then run the jets and re-test in an hour or so and see if you need to reduce further. PH Minus is the sole chemical used to reduce PH and Total Alkalinity in your hot tub.
