You have next to nothing in that tank!!!!!
(oh how I wish!)
Your fish waste would be nil, especially
with 3 HOB filters....
Your biggest waste producer would
probably be uneaten food or like me
veggie matter I feed my 3 plecos....
Just stir the bottom every so often
so the HOB filters can pull some of
the waste out and you should be fine.
A wet/dry filter is one that overflows
via a pre-filter box down over a medium
that allows a combinations of water/air
(hence wet/dry) for the growth of bacteria.
Then the water is pumped back our of the
sumb to the tank.... usually found on larger
tanks and saltwater systems...
I not only have the emperor 400s, but I have
3 whisper 3s, and a whisper 1 on other tanks.
I like the advantage of cleaning out the filter
medium and reusing them... and new ones
via online purchasing are not that expensive.
Not familar Aqua Clear filters....
