Is it true that air bubblers can remove c02?
Don't know anything about the bulb, but if it is a Compact Fluorescent, outputting 600 lumens, that is not too bad. I use two 10w GE Daylight CFL bulbs over my 20g, and they output 490 lumens each. Can you use two bulbs, or just one in your fixture?
I wouldn't think the light is the issue here. And the fert is not bad, though some nutrients are missing. What is your GH and pH? Is the rhizome buried in the substrate?
