Carbon filter media, and CO2

I have a wet/dry filter 20g ish, i have my equipment in there as well. i have my heater and co2 in the well under the bioballs area. My CO2 line has an air stone that i placed in an open ended pvc pipe to keep the bubbles from rising up above that, i also have my mechanical filter sponges placed on top of the PVC to further dissipate the bubbles from rising to the surface fast, i began using carbon recently to keep my water from tanning with all the wood i have in the tank. The carbon pack is on top of the mechanical sponges. Will this affect my CO2 will carbon absorb any co2 and or ferts i put into the tank? the wood i use is local drift wood from the creeks, it tans the water tea colored rapidly without the carbon. Suggestions? Thanks
