For PH Down - 1 mL/gallon of water will generally reduce your pH about 1 point. That's just a very rough estimate, but gives you a starting point. In imperial measurements, that's 0.2 tsp/gallon (1 tsp/5 gallons) will reduce the pH by 1 point.
For PH UP - PH Up is not potent stuff! It actually has a very weak effect. Compared to PH Down you will need to add much more PH Up to adjust the pH by the same amount.
