Cycling A New Filter

[Cheryl]

I just got a new canister filter and would like to set up a new tank with new substrate. How long do I need to leave the filter running on the cycled tank before I can assume it has all the necessary bacteria to support an uncycled tank?

I think people on here have said a month. Also you could run it for a while and then add some Floss out of the cycled filter as well ,that's what i did when i added an Eheim classic to my tank,then i removed the old Filter.
When you are adding it to a new tank,don't forget the Bacteria will die if you don't add fish or something to keep feeding it.

I would recommened a month aswell, longer if it is possible and practically to you. Like SilverLady says, you can always move some of the established filter media into the new filter at the end of the month, just to make extra sure.
