Thread: High PH low TA

  1. Back To Top    #1

    High PH low TA

    I have high PH 7.8+ and low TA 50ppm according to the test I did today. I just want to make sure I am doing the right thing...adding muriatic acid to lower the PH and Sodium Bicarbonate to increase the TA. Does that sound right?

    yep...baking soda will increase the TA with a minimal effect on the pH.

    Thank you, I thought that was right I just wanted someone to confirm it. I added the muriatic acid today, will hit it with baking soda tomorrow.

    Just note that if you raise the TA you increase the rate of pH rise so you may not want to raise it very much (assuming you are not using a net acidic source of chlorine).
