If you add, a bottle of carbonated water, it would be there, and gone as

and circulate....

In theory, Amano started out by putting one bottle in a 10g a day for
several weeks and it was then he realized pressurized CO2 would effectively
deliver the correct absorption of CO2 into the water....

What size bottle is that? I have used carbonated water to adjust the
pH of my replacement water and 1 bottle (2 liters) in 10 gallons would
push the pH so far down that it would kill everything. It has been my
experience that it takes about 1 cup per 8 gallons to adjust the pH
from a 7.8 - 8.2 solution down to 6.8 with a kH of 4.5 and gH of 5.

Ok, try this, take a 5g bucket, measure your pH... wait 4 hours measure pH
again...

for a double blind comparison, fill the bucket up again and measure pH for
baseline, this time, pour several bottles of your desire into it, measure pH
again.... wait 4 hrs, check pH again... my guess is the Co2 will make no
difference to it, because in 4 hrs, it's dissapated... gone... like it was
never there.... in a tank with circulation agitation, it's gone even
quicker....

Again, this is not borne out by my experience. I often airate the
mixture to thoroughly mix the hardening chemicals and the CO2 (club
soda) before introduction to my tank. It takes hours and hours to
make a measurable change in the pH level. I know this because when
first determining the mix levels, I added too much, and was shocked at
how FAST the soda water dropped the pH. It doesn't take much. And it
dissipates fairly slowly. I ended up re-mixing rather than wait
forever for the CO2 to dissipate.

YMMV,
