Definitely both if it were me. Just make sure that you run it until you move it over. BB need oxygen and food to survive so if you have no stock then add some ammonia. Once you move it put in 4ppm of ammonia and if your ammonia is 0 after 24 hrs your good. Just make the necessary water changes to bring ammonia, nitrite and nitrate down to good levels.Hi Everyone,
I’m working on setting up my new 125 (journal here).
I'll be breaking down my current 90G when I finish setting this one up, and I’m wondering if transferring my bio-media from my current filters to the new FX6 will provide adequate BB, or will I encounter a mini-cycle?
I only wonder because I don’t know just how much BB I’m going to lose from the substrate. I won’t be adding any bio-load from what I currently have, or at least not at first. Would you do a fishless cycle on the new tank before making the change, or just seed with the existing media and keep an eye on it?
