Loading a filter with bacteria

[IovaykInD]

How long should I put the filter in an established tank before I transfer it into a non-established tank?

I've heard two weeks. You might be able to speed it up a little if you put the bacteria spounges next to each other (assuming this is possible). You could also do this for a week then jump into a fishless cycle, which would go pretty fast and you would be able to add a full load of fish, not just a few.
