I know nothing about co2 at all, I'm starting a new 40 gallon really soon and its going to have 78 watts of t5 ho light. I've heard you don't need co2 with that lighting and I've also read that you do need c02 with that setup. Can someone clarify this and give me a clearer answer?
Also, if I needed co2, could it be as simple as this diy co2 in this video? CO2 for the first time. - YouTube
I'm not really interested in spending $300 + on co2
