NFC: Pressure (prolly off-topic. :)

Hey all.

I've got a 92G Corner tank, with an overflow system.  I've got a massive
pump on it, which, at the output end, just doesn't seem to give much flow.
It is rated at 2400 GPH.  I'd guess it is putting out less than 100 GPH.
The impeller is clean, etc. etc.  The trouble is... the way the former owner
set this tank up, the pump comes immediately after a sump, and then must
push water thru a Rainbow LifeGuard MechaniFilter, and a UV Steriliser.
Worse, it pumps up about 4", then back, then drops down, thru the
mechanifilter, up again (8"), left to the UV, up the UV (18"), right out of
the UV, and finally up the tank again.  All these bends, turns, rises and
falls are eating up my head pressure, and thus dropping my flow to next to
nil.
Now, my question is this:  If I move the pump to directly under the tank, so
the bends, rises, falls, etc. are all before the pump (and, thus, more or
less powered by the natural flow of water, I think?) would this give me
increased flow?  Obviously, when I rework this in a few days, I'm going to
try to minimise the twists, turns, rises, and falls, but ... I'm wondering
where the best place to put the pump is.

Joshua.
