I think that all trickle filters will outgas your co2 as long as you are dissolving the co2 through a reactor. Maybe if you mist, you might stand a chance of keeping your co2 up. Another thing to consider is a enclosed sump. That should work fine. You may not even need to do a trickle filter since they are geared more towards biological filtration. All the bio filtration you are gonna need should come from your plants.
