I am relatively new to the planted aquarium world and I have noticed in all my reading that 'poor CO2' gets the blame for much of what ails a planted aquarium. Particularly BBA and surface scum.
Well, I must have poor CO2 because I have both. My question is, what are we calling 'poor CO2'?
Using the kh tables my CO2 is staying right around 15 to 20 ppm. Does that range need to be narrower? Maybe 15 to 20 ppm is too low for 216 watts of light over a 75 gallon tank? I run the lights for 8.5 hours per day.
I would appreciate any insight you might have.
