CO2 Drop checker question

So I am looking at adding CO2 to my big tank, a 150 tall. While looking I found a CO2 Drop Checker from Nilocg that has the 4dkh solution with it. I am assuming that anything below 4dkh will show blue and anything above will be yellow.

What if my values for dkh and dgh are already high?

Here are the results of my last test. Yes, I know that our water is hard. I am thinking about mixing some RO water to get some of the levels down.

Hi Ph test: 8.2
Kh: 8 Drops (~142 ppm)
GH: 16-17 drops (~284.8 ppm)

In the mean time, would the drop checker actually do me any good with this water?
