I have a Danner 1800 gal pump in my 500 gallon pond. It draws from a
skimmer and pushes out to a waterfall w/biofalls. The pump is forever
clogging up and it is getting old having to get the pump out of the pond
and
remove the hoses every other week to clear it. (My 'barometer' that its
time to clean is when the waterfall slows to a trickle).

The skimmer has a cheesy basket in it which obviously allows too much
debris
to pass. Any suggestions on what I can add - perhaps an inline filter -
to
keep the pump clear?

Any chance of clearing the debris by rake (careful!) or hand if there is
that much of it?

Mechanisms can only do so much and your pump sounds like it'd have lots of
suck!
