Prefilter for small pond with a bead filter

We have a 500 gallon pond with plants and WAY too many fish (2 koi and
multiple shibunkin, gold fish and cats). The fish are named, so losing
them is not an option. Had small external filters (sponges) with a
submersible pump that finally just could not keep up with the job (or
at least I could not keep up with the frequent need to clean). The
Aquadyne bead filter with a jacuzzi 1 hp external pump is
Spectacular--"gin clear" water for the first time in years. Now the
problem:

As pond experts would have predicted, a new situation: the pump's leaf
basket gets so clogged that the outflow of the pump diminishes to
almost zero every day; now instead of cleaning the sponge filter once a
week, I need to clean the pump leaf basket every day. A mesh bag
around the intake pipe in the pond helps a bit, but then there is a lot
of crap left in the pond, and then the bag needs cleaning.

There is precious little space available for the filtration system, and
the Aquadyne has almost completely taken this up. Are there any
suggestions for some sort of prefiltration approach that consumes
little space, is efficient, is low effort, and can be untended for 1-2
weeks, and occupies little space?

Many Thanks in advance for your advice.

*Note: There are two *Koi-Lo's* on the pond and aquaria groups.

I use two black plastic pond-plant pots wired together like clam-shells with
the pump inside. It seldom needs cleaning and the pump doesn't clog with
litter. If the flow slows down after some weeks, I pull them up, open the
clam-shell and hose everything out. It's usually just collected mulm and
rinses out quickly and easily.

Many thanks for your help. I checked out your pond pages--most
impressive. I do have the predator thing figured out; if you would
like my input, please email me off line.

================================
We had a dreadful problem before we netted the ponds. We have the predators
under control using the fine black bird-nets. It's the only thing that
keeps *everything* out of the ponds and tubs that we have here. That
includes the herons, the kingfishers, the large snakes and bullfrogs, the
snapping turtles, the neighborhood dogs and even the occasional raccoon.
The small newts, tiny frogs and baby snakes do no harm to the larger fish.
These smaller critters can't get into the tall above-ground tubs where the
small fish are - but thanks for the offer. :-)

You may want to share the information HERE for the benefit of any lurkers
who may be having problems.

Plumb the intake line into a bucket, pot or some such container and
fill it with 'pea gravel'.

Good idea; will try. Many thanks!

Pump is external/out-of-pond correct? Very few in-pond pumps have leaf
traps.

How is the water now exiting the pond? Skimmer, bottom drain? If skimmer,
perhaps some netting that can catch it in the skimmer? Otherwise, you have
the water flow into a container, similar to what Jay was talking about. I'd
go with something at least 30 or more gallons. The bigger the less often
you will clean it, then have the pump draw mid-surface water from this
container. A pre-filter will also lessen how often you need to back flush
the aquadyne. Btw, watch your KH (buffering) with a pressure filter, they
work best when KH is 150-200. ~ jan

Many thanks for your response. Looked at your pond pages--impressive.
Water exiting pond via 1 1/2 inch tubing terminating in broad mesh
screen on bottom of pond. Material being trapped is relatively
small--appears to be fragments of floating plants rather than leaves.
30 gallon unit cosmetically unacceptable (like wires to the stereo in
the living room). Will watch the KH.

I'm not a cat lover, but I'm pretty sure you really shouldn't keep them in a
pond :-)

I'm not sure we'd predict it - most ponds probably don't have _that_ many
leaves, daily.

almost zero every day; now instead of cleaning the sponge filter once a

You need a surface skimmer...

But with that many leaves, I'm still doubt 1-2 weeks.
