How true. Cleaning the draft tube all the time is not needed and can be counter productive. Just dump the goop and let the tube develop a biofilm. When it builds up to the point were you see a decrease in output, or a increase in nitrates, it is time to clean it. After cleaning a dip in very hot water will help it return to normal in a shorter period,
