I keep some in my sump for a QT. I use a 10gal for quarantining new or diseased fish. I don't need it that often so I don't keep it going all the time. When I do I pull the rock out of my sump and do a quick 10 gallon water change from my DT. I use that water in the QT and have it up and running in about 15 minutes.
