Marine CO2 Level Calculator
* Special thanks to Boomer from
for his help.
This calculator estimates the concentration of carbon dioxide (CO2) in a marine (saltwater) aquarium given a few relevant parameters. Note that there are some 15-20 different approaches to performing this calculation and most of them agree to within a tenth of a part-per-million. The approach used by this calculator is taken from
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.
