My tap water is pH 7.2 and when we bought the house the TA was 110. I have brought the TA down to 90. My question is does a higher TA raise the pH more than a lower pH? Seems like I adjust the pH to 7.5 but in 3-5 days it starts to rise again. I lower never let it go above 7.8. What is raising the pH?
