gizmo hit on the problem and simon has the source which, in my case,
was the Fluval surface skimmer... it is difficult to get these things
to NOT suck in air.  I have finally given up on mine and just removed
the surface skimmer.  

My HOT filter kept "drying" out... water levels in the filter would
start out just fine but in less than 2 days the filter would be almost
completely dry.... water still pumping in and out, but VERY noisy and
lots of air mixed with the outflow...

Those darned adjusters on the Fluval surface skimmer do not seem to
work very well... water is either flowing very fast down the intake or
not flowing at all... when the water flow is faster, you get a large
intake of air as well.

Note: I also tried that skimmer on my Fluval 303 filter and had the
same problem you had, where the filter just locks up with too much
air.
