  I have a 26g tank with 2 Whisper 2 power filters hanging on it
and found that they were doing a great job with mechanical filtration
but not so great breking down ammonia and nitrate. My answer (CHEAP)
was to take an old breeding trap that was laying around, putting a hole in the bottom to fit the uplift tube of the filter through, and hanging it under the return of the whisper. I put a small amount of filter pad on the bottom of the trap so the gravel 
wouldn't fall through the slits in the trap, and filled it to 3/4 height
with clean gravel. No more problems with nitrite

  I have 2 whisper 2 power filters hanging on the back of my 26g tank,
and found that they were doing a fine job of mechanical filtration,
but not so great keeping the nitrites down. So, being the cheapskate
that I am, I looked for a cheap solution. What I did was I took an
old breeding trap (the kind with slits in the bottom), and turned it
into a little bio-filter. I cut out a hole in the bottom of the trap
to fit the uplift tube through, and hung the trap below the whisper
so the output would drain right into the trap. I put some dacron on
the bottom of the trap to keep gravel from falling through the slits
in the trap, and filled the rest to 3/4 height with gravel. It took
a little while to get going, but my problems are over! I used a cut
coat-hanger to hang the trap on the side (for strength). It really
seems to work good. I just thought this might be an idea someone
else could use.
