It is amazing how much ammonia a plant will assimilate. But I would get more plants, absolutely. But there are not many fish in this tank, I can only see one in the photo...course, my eyes are old and feeble
. Anyway, bacteria (if it is needed because there is more ammonia that the plants can use)colonizes every hard surface under water. There is more bacteria in a normal fish tank thoughtout the tank than ever in a filter. So that is not an issue. Second, more filtration does not mean more fish can live, which is the same in reverse of saying you need more filtration because there are more fish.
You don't want carbon in a filter in a planted tank, but at the beginning it will do no harm for a couple weeks. The carbon will wear out and become ineffective within a few weeks, depending upon the bio-load in the tank. Which leads me to ask why you are considering this filter rather than a simpler sponge type? I may have missed this earlier in the thread, but it is worth asking because simplicity is the better path.
