Which has better bio filteration.
The AC500 packed with ehiem substrate or the 2 biowheels on the Emperor 400!
then with a canster filled with the best media have great bio filteration even though it has no contact with air!
I am guessing its the AC500 loaded with media can almost act like a fully charged wetdry since the substrate is exposed to air! Any experts know the answer.
