That is quite a lot of light for no Co2.why do you need co2 with that light? I do not understand. sounds like your tank will do fine with that light and no ferts, or very little . I believe your over doing it ....... just my opinion. not everyone needs co2 and your light is perfect with out it.
why?? you can have 2 watts per gallon and no co2, in fact you do not need co2 with 2 watts per gallon. I am at just a hair more ( if you want to split hairs.) and it works wonders for my tank. why to much light?? no fish die, and my plants explode.... I say my tank is perfect !!That is quite a lot of light for no Co2.
