I'm looking for a more powerful filtration system for my 55 gal Oscar
tank. Although I vacuum and do partial water changes every 5 days or so,
I find my current bio-wheel filters to be inadequate. I did, at one
time, have an UGF in the tank but did not like it. I could not keep it
"healthy" with all the vacuuming I do. So putting one back in is out of
the question.
So, what I'm wondering, is should get more powerful bio-wheel filters to
increase my gph filtration or should I invest in a canister filter or
something else? What kind of setup has worked well for others. I need
some advice.

What sized biowheel system do you have? I use Penguin 330 in my 55s
with Oscars and it seems to work well. Penguin is updating it to a
350gph system, too.

If you're using a filter with 330gph or more, then your problem may not
be filtration but something else; overfeeding, too many fishes,
something like that. Another possibility (please people don't flame me
for this --) is that changing the water every five days may be too
frequent -- back off to every ten days or so. I doubt whether this is
the problem, because of the biowheels, but it's a possibility. Another
thing to think about is whether you've allowed enough time for the
biowheels to establish -- takes a few days for the bacteria to "thicken
up" on the paddles. In my experience, a Penguin 330 or an Emporer 400 is
plenty of filtration for an Oscar 55, so before you dole out a lot of
cash for a canister you may want to look at these other issues. --Mark
