Hey, I'm getting a new to me 33 gallon tank up and running.. I know about the nitrogen cycle and all the steps from my smaller tanks. This time I thought I would try to give it a little boost.. I pulled some filter media from my established 10 gallon. I sandwiched the established media, between the carbon and the biomax bags in my aquaclear300. How long should I leave that media in there to help get some colony grown in the new set-up?? Thanks again!
