It depends. Are they standard 24" bulbs or are they 30" bulbs?

do ytou know the wattages of the bulbs? the bubbles should be as small as possible so that it can mix with the water, if they are big they just float to the top and do nothing

I have seen recommendations to not use rapid rise yeast, but if you get bubbles, I think it works, and don't see a problem...

Measure kH and pH, and then figure out the CO2 level with this http://www.csd.net/~cgadd/aqua/art_plant_co2chart.htm to see if it works or not.

Regarding the light... I would say it is okay for low light plants, if you have decent reflectors for them.
