I think you are mis-reading the chart.  On the chart, the KH
values are listed in degrees.  If you had 8 degrees KH and a
pH of 6.8, then you'd have 38ppm CO2.

Your KH 80 probably means 80ppm, which is only 4.5 degrees KH.

Use the calculator above the chart to enter 80 ppm and pH 6.8,
and you'll get 21 ppm CO2.
