I started injecting CO2 when I started dosing the PPS Pro scheme. I did not increase CO2 when I started dosing EI because I was already blasting the CO2 at a fairly high rate - don't ask me what my bubble count is, I have no idea - too fast.
To get back to Tom's point about limiting factors: under high light, CO2 and ferts are limiting factors. With CO2 and livestock you can only inject CO2 up to the point where it is non lethal. That is your end point for CO2. After that you need to balance ferts and light. Given that the tropical fish most of us keep are very tolerant of a wide range of ferts you have a lot of wiggle room there. Concentrate on light and you are mostly there.
