Sure that is true.  But on what scale?  Keeping a
dozen tetras is not the same as keeping discus.  In
mass one adult discus is equivalent to how many
cardinal tetras?  A LOT.

In my opinion, discus without filtration is a bad
idea.  You will end up with bad discus.  The ability
of the plants to take care of fish waste will be
overwhelmed.

Bill, have you in fact raised discus without
filtration or significant water changes?  I would be
interested to hear about your direct experience.
