PH adjusters work simply by altering the pH of a solution. If the current pH is at 5 (slightly acidic) a solution of alkaline (pH UP) is added to raise the solution to the desired level. This also works in reverse.

45% Potassium Hydroxide is a fairly concentrated solution. Always test with small amounts at a time checking the PH level each time as well to see how much it was raised. Add small increments at a time until you reach the desired PH level.
