Apparently wet/drys are not good to use with CO2, all the turbulance and increased water surface allows the CO2 to escape too easily. Surface agitation is also bad, so the 110 is not the bestest idea. It seems like people are either going with cannisters, internal filters (like sponges attached to powerheads) or no filter at all.
Now, I am just learning most of this, so take my advise with a grain of salt. I am sure some of the more knowledgeable fellows here will point you in the right direction.
P.S. There are some plants that don't need extra CO2, so you can maybe go that route?
