Need filter ideas

[OrandaPond]

Hi everyone,
Does anyone know or have plans to construct a good filter for a small pond (120 gallons).

Go to my Koi web site and see if the Doc Filter is something you could build. For a small pond you might get away with a 30 gallon drum instead of a 55 gallon. I would not go any smaller.

the DIY section here has several plans easily downsized to a smaller container.... for example :https://www.gardenpondforum.com/koiguys-55-gallon-bio-filter-skippy-style-t4339.html

I have a 30 gal white barrel and it is working great for my 300 gal pond RDK
