Equilibrium pH Calculator
* Special thanks to Boomer from
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:
Millimeters of Mercury (torr)
Inches of Mercury (inHg)
Altitude in Feet (ft)
Altitude in Meters (m)
Atmospheric CO2 Level:
Carbonate Hardness (dKH)
Relative Specific Gravity (sg)
* Carbonate alkalinity can be determined by subtracting
alkalinity from the
alkalinity. If you cannot determine your borate alkalinity, you can report your total alkalinity here but the results will not be as accurate.
