I use carbon and Purigen. Carbon only last a day or 2 then becomes media with a high surface area. Purigen removes ammonia and makes the water like glass.
I use them both more for polishing than for filter bacteria etc.
The CO2 needs to be in the open water not in the rear chamber.

Awesome. That settles it Purigen + CO2 in the tank. I really appreciate all of the help everyone!!
