Yes, I'm doing tap water also. I'm using the commonly available red/yellow/green "drop counter chart" to determine my target. I'm not talking about adding buffer AFTER I inject CO2 to "chase the drop". I am looking to "nudge" the pH up a little. My tap water KH is 4, I am thinking a KH of 8 would result in a better pH range for my endlers. But trying to understand what to expect with a buffer. Would it change my starting pH (no CO2) and ending pH (@30ppm) by exactly the same amount?
This is a great little informative piece, thank you!!!
To my understanding, it should change your starting PH which should change your ending PH as well. Read through the link at the bottom. There's a lot of science there that I can't explain
