It's depends on how many plants you're going to have. No point in a getting rid of your major bio. filter for one plant, you know? Also, if it's only one or two plants, there'd be enough CO2 even with lots of surface agitation.
See how well your plant growth is first before you do something 'drastic' like that. Even if you find that your plants aren't growing well, or they even flat out die, it could be any number of other factors excluding CO2 deficiency in the water (macro, micro nut., too much sun, too little sun, and so on).
Maybe you might even look into those DIY CO2 chambers? Basically entails a container (soda bottles usually used) with a mixture of water, sugar, yeast, and baking soda. Can be done without baking soda, but the b.soda makes it more stable such as, you won't be getting bursts of CO2, or you won't get a surge of CO2 just in the beginning with little/minimal after that. Basically, the yeast feeds on the sugar, and voila, CO2 is produced traveling up container through tubing you've put on into the tank. A common complaint regarding such DIY devices is that you can't control the size and diffusion of the CO2 bubbles well.
Good luck, live plants in an aquarium are the best!
