A lot of people confuse a QT with a HT (hospital tank).
I put some rocks, PVC
elbows and a bio filter pad I keep in my sump into the qt. If I determine treatment is required (hypo salinity only, I never use copper) then the rocks and bio pads are removed and cleaned (and dried for a couple months minimum). Meanwhile i hypo the qt making it now a ht. You want to minimize BB during hypo to limit die off during treatment.
After the qt the tank and PVC
are cleaned and the tank is put back into the shed until next time. The PVC
is dried and later put back into the sump to cure for next time.
