Re: your advice needed for test results
Since you need to raise BOTH pH and total alkalinity I would suggest you raise the pH with Sodium Carbonate (ph increaser, washing soda from the grocery store) until the pH is where it is supposed to be or until the TA is in the proper range since it will do both at once. With your posted numbers it will most likely get you pH up before it gets the TA to the desired range. Then make further increases to TA with baking soda and finally make any final adjustments to your pH with either acid or borax.
