I had to make a Big Al's purchase anyway, so to "save on shipping" I just ordered a new light strip. That's the excuse I keep telling myself anyway. I ordered a 110 Watt Power Compact strip. More specifically, this one. It will put me right at 2 wpg. I know that anything above 2 wpg and you should use CO2. Do I need to worry about that if I am right at 2 wpg?
