Jerry Hames' Koi pond is approximately 17,000
gallons, with dimensions of 16' x 24' and 6' deep. He has about
35 Koi ranging in size from 8 inches to about 2 feet. Jerry installed
two different and separate filter systems, a Linn Wav pump on one and a
Sequence pump on the other.
Two 3" bottom drains feed a settling tank, that feeds
another settling tank, and is then pumped into a Fluidbead filter.
This filter works under pressure, and the water returns through 6 UV lights,
adding up to 240 watts, to the pond about 1' under the surface. A
1 1/2" pipe runs a skimmer keeping the surface dirt and such off the pond.
This water goes through a large leaf catcher, and is then pumped into a
300 gallon filter that has plastic string type material for a filter medium.
It flows from the top of the filter down a large pipe and then up through
the media and gravity flows to the waterfall, and then into the pond.
The water fall can be bypassed to a discharge about 1' under the pond surface
during the winter to prevent excessive cooldown.
Jerry has a large frame with a shade cloth over about
80% of the pond. This helps control the algae, and keeps the Koi
from losing color. The overflow pipe keeps the water at a predetermined
level. A large air stone gives the pond plenty of oxygen for those
hot days, and evening time when there can be a shortage of oxygen in the
pond.
