This is probably a dumb question.
I bought two drop checkers on ebay and some 4dKH solution to put in them.
There are three colors on the color chart. Blue then green and then yellow at the top.
How do you determine the CO2 concentration using only three measurements?

I assume blue is no CO2, green is supposedly the right concentration and yellow is too high.

I’ve done a search and cannot seem to find what the colors indicate.

You are correct in your thinking.

did you order the actual 4dkh solution or was it one of those kits with a drop checker and "ph reagent"

I bought it on another forum from an officer in the Air Force.
I'm beginning to wonder if it's good.
I just pulled out the other one, filled with tank water and put it next to the one w/4dKH just to compare.

Thank you
