I'm sure this gets tossed around every week, but
in searching back posts, I could not find much on
specific recommendations.

I have a 750 gallon pond in Los Angeles, two 16"
Koi, an 8" Comet and some minnows.

It is an established pond (5 years or so) with
very good vegetation.

I would like to get an external filter to replace
my cheap immersed filter. My current pump has a
350 gal/hr rating.

I have browsed the various sites, and there is a
huge range/variety of filters out there from which
to choose. I would like your recommendations,
advice or experiences with different brands or
models.

Currently I am looking at:

o Aquapur 18 @$199 (pressurized)

o Medium Fish Mate Bio Pond Filter @$120

o Laguna PowerFlo 4500 External Filter @$90

o Clear Stream 1200 @$120 (pressurized)

but would consider any other brands or models.

Any advice you could provide would be greatly
appreciated. I will spend more if the additional
cost is warranted.

best,

doug
