One would expect that someone with as much experience with Koi as Ed Fujimoto would have beautiful Koi and a wonderful pond. We were not disappointed.
Ed's pond was one of the first gunite ponds in the area and holds around
6000 gallons. The amount varies depending on the water level which Ed
controls by placing various height dams between the pond and the downflow
filter housed under the deck. The filter is 4' x 8' x 3' deep and filled
with pea gravel. The water is then pumped to the top of the hill where
it flows through an aerator (6" vertical pipe with hair curlers) and then
down the waterfall back to the pond. Ed rarely has a problem with
green water like the rest of us. The large filter is most likely the
biggest contributor to this.
Ed suffered some loss of fish a few years back due to sea otters that came
from the Puget Sound which Ed's place sits on. Most of the fish in the
pond now were fry of one of the fish lost in the attack. The fish had
just been returned to the pond after spawning when the attack occurred. Ed
installed an electric fence around the pond after the incident which stopped
the otters cold. He eventually removed most of the fence, but left
the sections that border the side closest to the Puget Sound and hasn't had
a problem yet. You can see some of the fence on the edge of the deck
in the third picture above. I didn't check to see if it was energized
or not.
