CO2 in low light?

How "low" of a light are we talking?

Even in a low lighting aquarium (provided, we are not at a point where there is insufficient light for plants to even grow), CO2 is beneficial.

Low light as in 15-20 watts in my 10g tanks... so less than 2 wpg... (i know wpg is a faulty way of measure... but its classic... xD)

by adding co2 to the tank you will, (and I pause) allow the plant to photosynthesize as much as they can with the given light. if there is enough atmospheric Co2 being turned into your tank it wont benifit, if it can photosynthesize more co2 than what is otherwise available it will.

aka thats nearly an impossible question to answer.

ok... =D Thanks, thats what i figured, it can only use as much as the light allows! =)

Do a search for the Tropica study on CO2 and plants. Tom Barr usually has a link in his posts. It's not as simple as your statement.
