  • Use a freshwater pH test kit to determine the pH of the aquarium (not included)
  • To raise the pH, add 4 drops of pH Up for every 1 gal. (3.8 L) of aquarium water
  • To lower the pH, add 2 drops of pH Down for every 1 gal. (3.8 L) of aquarium water
  • Take another pH reading before making another addition of pH Adjuster
  • If fish are present in the aquarium, do not change the pH more than 0.2 in a 24 hour period (for example from 7.2 to 7.0). The number of doses required may depend on the carbonate hardness level and the desired pH.
