Is CO2 absolutely necessary?

Hi, I have a 24 gal Nanocube set up for a planted tank and was just wondering if it was absolutely necessary to set up CO2 for it (72 watt lighting) or will my dose of Excel Flourish every other day be sufficient? I also have a bottle of Natural Aquarium Vital that I put in every now and then. I don't think I have that many fast-growers in there (crypts, amazons, giant ambulia, moss, chain sword) although I do have a few patches of dwarf hairgrass which don't seem to be doing all that well...

You will need C02 if you plan to use 72w on a 24g, half of that would be much better with just some excel, not the full 72.
