Determine the pH of aquarium water with an API pH Test Kit.

  • To raise pH, add ½ teaspoon (2.5 ml) for each 95L of aquarium water
  • For larger aquariums, add 1 teaspoon (5 ml) for each 180L of aquarium water
  • Take another pH reading before adding another dose of pH Up
  • Some fish may be sensitive to pH adjustments greater than 0.2 in a 24 hour period, so changes of this magnitude should be done with extreme care
