Buyer beware. Pond filters are notoriously over rated. They will usually
take care of a pond that is half as big as they say, and that is if you
don't overstock too much. I would get a filter rated for at least 2000-3000
gallons, if I bought one of the commercial filters. Jim and Phyllis
described the veggie filter, and it needs to be at least 10% of the surface
area of the pond or larger. Larger is better. Gives slower flow rates,
better cleaning, and more room for more plants.

I've done some searching around and I've found various biological
filtration systems available and I was hoping for some recommendations
for a 1000 Gallon pond that WILL have a 1200-1800 GPH pump. It needs
to be external and small / and/or buriable. Preferrably one of the all
in one that's not heinously expensive. Probably looking at something
pressurized and either with a backflush mechanism or cleanable media.
(Preferrably backflush, for obvious reasons.)

Unfortunately, I don't have a bottom drain, so that's going to screw
with the asthetics as the pond is built up about 20" high around the
edges in a circle. (If anyone has any bright ideas on hiding all the
power / tubing, I'd love to hear that too. ;-)

Also looking for recommendations for on-line vendors, etc. I was
impressed with what PondPetsUSA.com has to offer, I was hoping to get
some more information before I leap off a cliff and buy the wrong
thing.

Any help you can lend would be greatly appreciated.

Thanks,

DC
