Nothing actually "requires" additional CO2 to be added. Egeria (AKA anacharis or elodea) is really easy to grow. You can go high tech with things like pressurized CO2, EI dosing of fertilizers, etc. Or, you can go low tech just doing water changes, minimal fertilizing, and let nature take it's course! If plants have the basics: proper light, nutrients, and CO2, then most will grow without additional effort or expense! If you want faster growth, with more maintenance, or special plants with strict requirements, then you can always add complexity. I'm somewhere in the middle - I consider myself "medium" tech regarding my planted tank. Start simple, get the plants going then decide how complicated you want it!
Don't forget to read the stickies posted here! They are a great help. Also do a search for other posts by forum member Byron. His posts are a source of outstanding information.
