Mechnanical filter can do so much. You can inspect how your filter work.
Next time you stir up those pollutant, not all get suck up by your filter
but settle down on your substrate or whatever it land on - especially the
heavy or big one. BUT what if you have a natural filteration that will
remove those land on your substrate and rock. There will be too many
decaying thing laying around and less nutrient to be release. Think about
it. I believe you using "Fresh Water" method on how to clean / filter your
Fresh Water Tank.

But everything I see in marine tank instruction and/or sales always includes
all three filters: mechnical, chemical, bio. Although I can understand how
some may adopt an alternate philosophy do to away with mechanical (as explained
here), its not actually considered 'wrong' for marine tanks, is it? Its still
the conventional wisdom for marine, no?

And we havent even talked about chemical. I see Marc has done away with that
too. Whats the theory behind that? Chemical is just for odor elimination, isnt
it? So there's no danger without it, just smells. So, Marc, are you living
with tank odors, or does your system handle that naturally too?




Remove the Bio-ball or media where it house very effecient bacteria where it
live and convert to nitrate.
You will need to slowly convert from trickle to DSB sump or Refugium. Normal
light will be ok for macro algae.

Does DSB house ALL types of necessary bacteria? So it can stand alone as
biofilter? Or is LR needed with it?

I gotta say, I've been at this over 2 years now, and research constantly, but
every now and then, I get input that reduces me back to feeling like I know
nothing :-)
