Desired CO2 ppm?

I have just recently set up a pressurized CO2 system with an inline reactor on the outflow side of the cannister filter on a 72 gallon bowfront. All is working well. The pH is dropping, and I haven't checked the kH yet.

I was wondering what the desired CO2 levels are for a moderate to high planted tank. I have looked at the chart correlating pH and kH to determine the CO2 level, but I didn't know if the "ideal" values of CO2 would be high enough.

30 ppm is what most of us shoot for.
