Will alkaline substrate and rock interfere with CO2 readings using the KH - pH chart?
I have dialed up CO2 by 50% using Tunze CO2 reactor from 1 bps to 1.5 bps but could not detect a change in CO2 according to the KH-pH chart. Note that 1 bps in the Tunze reactor is about double to triple the bubble size of a regular bubble counter from the regulator

My 75 gal pre and post CO2 pH are 7.6 and 7.0, respectively, regardless of the CO2 injection rate. But I am certain CO2 is getting into the system as I can observe increase in plant growth rate and faster dissolution of my limestone rocks. I have dolomite substrate which is likely dissolving away faster but I won't be able to detect.
My tap KH is around 4 and tank KH is consistently 5. My tap GH is around 5 and tank GH ranged between 10 to 15. I do not add GH, and apparently the alkaline substrate and rock affect the GH, but barely the KH.
I am wondering if alkaline substrate and rock can interfere with CO2 readings based on the KH-pH chart. I also have a CO2 drop checker but the color stays nearly the same, always blue green.
