I recently setup a QT tank and my first set of fish will be graduating to the display tank soon. What do people do with the ceramic filter media and plastic filter sponge when the QT tank is not in use? Do people just run the QT tank empty? Or can I put the media and sponge into a bucket and keep the beneficial bacteria it alive that way? I assume it is a bad idea to try to rinse the media and sponge and place it back into the display sump.
