Equilibrium pH Calculator

* Special thanks to Boomer from www.reefcentral.com for his help.

This calculator estimates the equilibrium pH of your aquarium assuming it is thoroughly aerated. When your actual pH is below this value, increased aeration will will increase your pH. When your actual pH is above this value, increased aeration will decrease your pH.

Atmospheric Pressure or Altitude:

Atmospheric CO2 Level:

Carbonate* Alkalinity:

Water Salinity:

 pH Units

* Carbonate alkalinity can be determined by subtracting borate alkalinity from the total alkalinity. If you cannot determine your borate alkalinity, you can report your total alkalinity here but the results will not be as accurate.
