Kohaku are arguably one of the favourite if not the most popular Koi kept in the hobby today. The very reason for this is not hard to fathom - a good quality Kohaku with crisp clean red (hi) patterns on a snow white body background makes for a stunning sight, and unusual for any fish."

Improper seasonal feeding can lead to a build-up of toxic ammonia, which stresses fish and reduces their winter survivability. When the water temperature drops to approximately 65� F, start feeding with Spring & Autumn Pond Food. This type of fish food is better suited for the dietary requirements of pond fish in cool water and won’t pollute the water with excess ammonia. Some water gardeners continue to feed their fish until they no longer come to the surface. I stop feeding my pond fish when the water falls below 42� F. "

Pond water will flow from the bottom drains of the pond up the pipes in the direction of the red arrow as shown.
An ideal settlement chamber will be sloped from shallow to deep. The bottom drains will all face upwards and be located in the deep end of the settlement chamber, whilst at the opposite side on the shallow end of the chamber the exit pipe that feeds the primary mechanical filter stage will be located.
Being located higher than the bottom drain pipes increases the likelihood of the solids entering into the settlement chamber being collected in the deep end.
And YES, this does mean you need a waste flush valve located somewhere near the deep end of the settlement chamber so that you can flush all these nasty solids straight out and off to waste.
Settlement chambers - essential ...
What is a settlement chamber?

We have seen that bottom drains are essential in a Koi pond. We have also seen that 110 mm piping is the way to go on bottom drains and that we don't want pumps in the water path before mechanical filtration takes place.
A settlement chamber is a smallish concrete chamber that has the 110 mm bottom drain pipes entering the bottom of the chamber vertically.
