On my 10 gallon I have a penguin bio wheel mini 100, and I decided to upgrade to an aqua clear 30. Should I leave my penguin running with the aqua clear for a couple weeks? Or should I get rid of the penguin right away? My thinking is that the aqua clear doesn't have any bacteria yet and if I pull the penguin out I'm taking a bunch of bacteria out of the tank. I know there is a load of bacteria in the tank itself, I just don't want to cause a mini cycle.
