CO2 drops PH..

so i start my tanks with a 0.8 PH drop of co2 injection and adjust the co2 level from there
generally my tank take a 1.2-1.4 ph drop to have sufficient co2 levels.
I have lots of light

co2 levels are really determined by the plants, if they are growin properly for their light level. then you are sufficient. if leaves are curly, discolored, stunted in size, etc but you know you have enough nutrients, then this is co2
