Yup but I don't think many people have as much aeration as you. The CO2 levels outside do change over day vs night and seasonally so that variability should still be there.

I think I am going to attempt to use an IR CO2 monitor to float on my sump and give a real time read out of the CO2 levels dissolved in a small headspace. Then a .001 pH monitor to get a nice resolution on the pH. My salinity and temperature are rock solid and can be removed from the equation. Should work nicely!

All I want is for the system to text me when my approximated alkalinity is low. Then I will go in and manually raise the dosing if it is actually necessary. Controlling pH seems like a risky risky business to me.
