Can someone tell me how high I can go with the CO2? It's my first time using CO2, so I'm still a bit unsure, and I don't want to mess it up now by giving too much and ruining everything.

From what I read, 1,200 to 2,000ppm is good for your plant, but even 800ppm is okay. You definitely do not want to go below 400ppm though. Another thing to consider is that the plant can only use CO2 properly if it is getting enough light.
