The title says it all.

If you want them to look like an Amano tank or many of the other ones you see in pictures........... It helps, though, to keep the surface agitation to a minimum (less degassing of CO2). Also, it depends on the types of plants you're using. You could certainly grow a tankful of water sprite without CO2 supplements for instance!

That sounds good. From what I've been reading, it sounds rather expensive to run a CO2 system.
