So ive just found out that airstones drive out co2. Crap..
How do you aerate tanks now? Or do you not do it at all..

No, you make sure your filter outlet (be it an internal or external filter) is near the surface of the water so that it creates ripples on the surface - or surface agitation as you'll hear it referred to.
That will aerate the tank as much as you need it to mate.
