optimal CO2 (ppm) level for fastest plant growth


I am really needing help since I couldn't find any good information on this so far. I have a plants-only aquarium and since I know that CO2 is good for plant growth I have arrived at the following question:

What is the best (highest) value of CO2 (in ppm) to have the fastest plant growth speed.
If you somehow know this for my plant specifically, then that would be even better: limnophila sessiliflora

I assumed that the more CO2 the better, but I assume there needs to be a limit when the water turns too acidic?

From the information that I could find online it said that 30ppm is good because then itís good both for plants and fish but since I donít have any fish in my tank I was curious how much I can actually raise the CO2 ppm value.

Thank you for your help in advance!
