A great way to avoid making the unwanted bacteria resistant and to prevent loss of good bacteria;
> Cycle the filter media in another tank, using underdosages
> Transfer the cycled media into the tank that needs treatment
> Now you have resistant colonies so you can safely kill the bad bacteria!
I always cycle with melaleuca and I try to always have cycled filter media ready to replace old media. That way I don't have to re-cycle my big tanks too often. (this is a great way to put spare undersized tanks to use!)
