So its been almost 2.5 months since velvet wiped out all the fish in my 55, now planning on getting everything back together. I have a question about setting up a QT. I'm currently using a eheim cannister filter, which I plan on changing to a sump sometime in the new year, but can I place a few bio balls somewhere inside the the filter media to seed it and then place them in HOB filter for the QT when needed?
