I don't remember if you mentioned what size tank you are using this on. I would recommend going with the AC30, for the little bit more in price you will get better flow rate and a larger basket for materials both equal faster cleaning and longer times between changes.
I'm am in now way an expert when it comes to plants, but I don't think there is a connection between plants and carbon. as I understand it Plants will remove nitrates
, and other minerals most of which carbon does not filter. Carbon will be good for heavy metals (lead, copper, zink etc), chlorine and the like (hopefully the last was already neutralized before being added to the tank)
The good thing about Plants is that they use up the nutrients that algae would normally consume. I have trouble growing plants in my tank because the goldfish love to pull them up.
