This is part of the problem with these kinds of issues. It is all chemistry, terms like pH, alkalinity, the use of equivalents, the reactions that take place…
I do not know if I am smart enough to explain this.
What always intrigues me is why the thing that can be easily observed,
- in this case that CO2 in solution cannot be increased or decreased by manipulating pH without the use of CO2,
- has to be explained in depth.
- However, the position that contradicts simple observation does not require explanation.
Let me give this a little thought, painful though that may be.
It might help me if someone could explain why anyone thinks, based on your observations or explanations why the CO2 should be manipulated by adjusting pH.
