He's using 2 15w CF lights, a good amount of light for a 10g tank and around where CO2 becomes more important.
The best way to fight algae is to have a large mass of healthy plants, and the best way to get them growing is to add CO2. This is true in both low and high light levels, adding CO2 in a low light tank will not promote algae. I can't think of a scenario where lack of CO2 is a good thing.
