Ahh, 66g tank, 48x18x18 ? I got one of those. Nice size. Not so big
you can't put it anywhere on the floor and not too small for serious
decorating. That last filter is almost x10 tank volumes. At 1600L/h you
were already in the ballpark, but with an Oscar, too much filtration can
sometimes be just right ;~). The extra pickup power picks up and they
usually have a relative size (big) biological filter. Watch that the
little guy has a place shielded from the turbulence to sleep ;~)

Thanks for info, NetMax. I bought the 2400L/h one because it was
cheaper than most. Hopefully the pump thing on it won't break in 6
months, because I've had that experience before with buying those
aerator pumps from K-mart!! The pump still makes noise, but there aint
no air coming out!
I really hope this one is a good one. I spent AU$35.50 on it including
shipping. I think that's quite expensive, I've only ever had corner
filters and my old 60L tank filter had just a sponge filter that cost
$15 from the petstore, so it was already overpriced!! I'll have to
have a serious look at my fish addiction if I one day find myself
buying one of those $150 Eheim external canister filters - OMG, so out
of my price range.
My tank is 48 long, 16 wide, 18 high I think. Hopefully my oscar won't
have too much trouble turning around if he gets to be at the larger end
of the scale.

It's better to have some redundancy in your filtration system, by having
more than one filter running, so anything else you could connect will become
your insurance policy.
Aquarium filters are generally a good investment. While expensive, they can
last a long time and they do perform a vital function. I only buy filters
on sale, either at auctions or during sales events at stores. I currently
have a Pro 60 and an Emperor 400 still in a box from two different store
liquidations. I'm sure I'll have a tank ready for them in a few years ;~).
