The CO2 vs pH/KH chart works whether you inject CO2 or not, but only if the water you are checking has only carbonates affecting its alkalinity and only CO2 affecting the acidity. That keeps the table from being accurate for most aquarium water, but it is accurate for a drop checker with known KH distilled or DI water in it.
