Whether you need co2 really depends on whether you have high light and how much you intend to fertilize. That in turn determines what kind of plants you can grow successfully. As long as you're set up with a low-medium light and don't intend to fertilize frequently, if at all, then you'll be fine with growing low-med light plants and no co2.

Looks like a nice home for your CDPs.
