Sorry. I'm thinking about pulling everyone to a new qt/hospital tank for id the dt of ick, and then ensure qt for all new fish - kind of a start over. Seeing my DT is still new I want to carry over as much BB as I can. I was wondering if while going fishless in the DT do I need to run mechanical filtration or if the protein skimmer will be enough, and for how long. There will be a few invert left but no fish. It is a 90 gallon and the skimmer is a bh2000. My mechanical is an AC110, and this is what I want to place on the QT/hospital.
Would that be enough BB for kick start the hospital tank or will I cycle?
I'm looking at a 40 breeder.
