How long would you run a filter on a running tank to develop the bacteria to put it on a new tank?

Thanks guys. Seeing as the filter is an xp3 and I already have an xp3 and xp4 I will swap the running xp3 for the new one. Then use the one that had been running on the new tank.

That should cycle your tank in no time....test you parameters with the used XP3 running for a day (Ammonia and Nitrate....Nitrite optional) wait 4-5 days and test your parameters again.
