This morning I added boric acid and cyuranic acid to the pool. The readings before were FC: 6, pH: 7.5, TA: 90, CYA: 40. I added 15 lbs of boric acid duda diesel and 37 oz of dry stabilizer. Aftern5 hours the pH was 7.2, TA was 100. I didn't expect those to change. Was that unrealistic?
 
The dry stabilizer probably lowered your pH more than the boric acid.

They are both mild acids.
 
With a TA of 100 I would leave it as is and the pH will rise naturally.
