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
