Aquarium Advice Addict
For a QT i use a 10 gal tank with a HOB (hang on back) filter and a couple of PVC fittings for the fish to hide in The HOB stays on my sump filled with poly-fill (no cycle in the QT) When the QTis done everything gets cleaned with vinegar and new poly-fill is added to the HOB t be reseeded for the next QT.
