How I built my Barrel Filter

I built this filter for a 750 gallon above-ground pond with a 2 X 10 foot section extending 24" below ground. The filter is in it's second year, and sustains 4 Koi, ranging from 12 to 18", and about 30 goldfish (started out with 6! )

"The basic ingredients of a Barrel Filter - A barrel, 1/2 PVC pipe and a piece of plastic grating from a flourescent light fixture(and your choice of media... I used small black lava rock.)"

"Assembled and ready for the screen"

"Making a Hoop for the screen. Wrap the hoop with cheap plastic window screen and sew it to the hoop to hold it in place."

"Screen in place, ready for media"

"Plumbing installed"

"The finished(for now...) product"
