Again, I agree.

Again, I agree. Folks seem to buy the lights first, then get iron and
nutrients next, then they fight , kick, scream and whine to no end about not
using CO2, or getting around it. I'm always amazed at the reasons folks do
not get CO2 or do not want to use it but have no problem rationalizing a
100-400$ lighting PC set up when the NO T-8's and T-12s work although
bigger. I agree that CO2 is the single best thing for helping a plant tank
in most cases.
