This has been fixed. I added in a line saying that smaller tanks are essentially cost ineffective due to the cost/pound of gas.

I'd like to think of them as two separate ideas. A diffuser is recommended (but not necessary), while diffusion of the CO2 tank (regardless of how you want to diffuse it) is essential.

Some people opt to use an inline reactor, or even sticking the CO2 line near their filter intake, both of which are diffusion methods, but not a diffuser, per se.
