Me again!

I'm getting confused with filters and air pumps ... do you need both?

Say I had a Fluval 2 plus filter ... do I need an air pump as well, or does the filter do the aeration as well?

Because I've started with a Bi-orb, I really don't understand how things work in a standard tank.

Thanks for helping with all my dopey questions!
