Hi I've heard about dennis wong method of adjusting co2 being the most correct one if u are within 1-10 kh, what is your opinion on that?

I've read
"A general good range to target is a 1 full point pH change. So for example, if your tank's pH starts at 7.5, you would target a pH of 6.5 for when CO2 hits saturation during CO2 injection. This would give you about 30+ppm of CO2 for tanks where the KH value is between 1 to 10 degrees KH."

What would be the formula for this one?
