I'm in the process of switching from an Emperor 280 HOB filter to an Eheim 2215 canister on my 46 gallon bowfront.
What I'm wondering is should I leave the Emperor on for a month or two until the biological filter matures in the Eheim? If I simply remove the Emperor and install the Eheim, I will have no biological filtration for a while...right?
Also, without the surface agitation of the Emperor, is the only source of fresh oxygen in the tank from the plants?
