What will remove CO2? If you're referring to aerating the tank, then yes and no. Aerating will remove CO2 IF
CO2 is being dosed into the tank, OR
if there's enough fish that the CO2 produced is higher than the equilibrium concentration. However, if neither of those are the case, then aerating will replenish the CO2 that's being used by the plants.

Sorry, I guess it just sounded very sarcastic. No, you can't have too much O2 in the tank. And it would be very difficult to oversaturate the water with oxygen the way a typical fish tank is set up.
