  • The primary functions of pH Buffers are to resist pH-Drop (acidification), and to hold the pH at a given target pH.
  • To lower the pH and hold it at 6.5:
    • Add 1 scoopful (5 grams) of this buffer / 10 Gal. (37.8 L).
  • To raise the pH and hold it at 6.5:
    • First adjust pH to 6.5 with an increaser (MICROBE-LIFT/pH Increase) and then add 1 scoopful (5 grams) of this buffer/10 Gal. (37.8 L). Check your pH regularly and add Buffer when needed.
  • Note: Pre-dissolve buffer in a small amount of bottled or dechlorinated tap water and introduce to your aquarium.

* A scoop is enclosed for your convenience.
