Are you running a filter? A good thing to use in your main tank is a sponge filter. That way when you need to set up a QT, you have a cycled filter for it ready to go.
Tank water does not have the beneficial bacteria in it that you need. The filter,gravel, and surfaces of you established tank does. Adding tank water really does nothing to cycle your QT.
So, if the gravel is form your cycled tank, I would just add your fish, after a complete water change to remove the ammonia you added.
If the gravel is not from your established tank, add some filter media from your established tank to the filter that you hopefully have on your QT.
If you do not have a filter on your QT, get one.
What are you treating your sick fish for? Some meds will kill off all the BB anyway,so having a cycled tank is pointless.
If the meds you are using, do not kill of the BB, then I would add your fish, and start treating it. I would also get some Seachem Stability, and throw the stress zyme out. Just follow the directions on the Stability, and you should be fine.
Shake the bottle of Stability VERY well. It should look milky white when you add it.
If for some reason you cannot keep a extra filter on your main tank to use for a QT, keeping Stability in hand should suit your needs.
