So I am wondering how much carbon any given coral can sequester given that carbon dioxide dissolves in water and forms carbonic acid, and coral uses that carbonic acid in their own calcification process given by this equation.
$$\ce{Ca^{2+} +2HCO3- -> CaCO3 + H2O + CO2}$$
Given the amount of concentration of carbon dioxide that is in the atmosphere currently, how much net carbon can one coral organism sequester per year?
Just as a note, I am not talking about coral reefs as a whole, but just one coral organism. Obviously a lot of assumptions must be made, so please just include them in your answer please. Thank you!
