I set up a bare-bottom quarantine tank and used old water from my main display so I'd have a fully cycled tank. I also took a piece of filter media out of my cannister filter and set it on the bottom of the tank.
The question is this: I don't have any critter in the tank right now, will the biological filter (specifically the ammonia oxidizing bacteria and nitrite oxidizing bacteria) survive if there is no bio load on the tank or will the ammonia oxidizing bacteria die off with no ammonia source?
