I know that a heavily planted "Dutch Style" tank can be run without a
separate biological filter. And in a properly maintained plant tank,
chemical filtration is generally not desirable or even necessary (water
changes to the work).
But aren't you missing the benefit of mechanical filtration - even without a
heavy fish load and possible overfeeding, plants do produce detritus. Do you
just leave it in the tank to decay? Not all filter units are noisy. And a
mechanical filter will not remove any nutrients from your tank (it might
remove some nutrient precusor products).
What do you use to provide water circulation in your filterless tanks?
