[Wet Thumb Forum]-Switching to canister filter...

[imported_Sam]

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?

I would leave it in place, but then again if your tank is heavily planted it may not make a difference. As for the O2 question. Maybe. I always have a Bio-Wheel filter running for just this reason. I know I lose some CO2 due to the Bio-Wheel but gas is cheap.

I'd leave the HOB on for a few weeks
while the other filter builds up some bacteria.
Although, like Rex said, in an established heavily planted
tank the ammonia may not make it into the filter.
