What's your tank setup like? How are you adding carbon exactly?

I'm planning on using a diffuser just totally new on this and unsure of what size I need. I have a 20lb bottle

I'm not really sure what you're asking, but the best way to get your CO2 dialed in is to start low, and use a drop checker to determine CO2 levels. You can increase your CO2 a little bit every day until you get stable CO2 at a level you like.
