Co2 and airstone-will they cancel eachother out?

I have been running Co2 in my tank, but i think it is too much for my fish. Or they just need a little extra O2. If I have the Co2 running, and an airstone, will they cancel eachother out? As in, will the airstone keep the dissolved Co2 level down too low for my plants to use?
Thank you!

if you run an airstone, the co2 will off-gas faster, and you will have lower levels. But you will also have higher oxygen levels, which are important for the fish. If you add an airstone, and increas the amount of co2 you dose, then you can have high oxygen levels, and high co2 levels which will keep plants and fish happy.
