Tip Adjusting pH using pH+ or pH-

Do you want to raise or lower the pH by using pH+ or pH-? Then dilute a small amount of pH+ or pH- in a cup to make judging the dosage easier. Try to get the pH right the first time. Using a lot of pH+ or pH- one after the other will disrupt the concentration of bicarbonate in the water and affect its buffering capacities negatively.
