You are quoting stocking levels from a water garden site NOT A KOI POND SITE.
Serious, your pond is made for a few goldfish, NOT koi. A constant drip system on the water garden that you have will help control the nitrites TEMPORARELY, there is no quick fix for what you have.
A KOI POND, has external pumps and filtration, it has bottom drains, jets, minimum depth of 4 feet. You can push a system to handle one koi per hundred gallons, but you would need triple the pond volume in filtration.
Questions:
1. Do you have a bottom drain?
2. What type & size filter ?
3. What type & size pump ?
4. Do you have an air pump ?
5. What do you feed the koi ?
6. Do you have plants in pond ?
7. Do you do weekly water changes?
8. Do you have rocks on the bottom of pond?
9. Do you have a waterfall for oxygen?
10. Would you make a full grown german shepard life in your bathroom?

Getting rid of the Koi is a great answer to get the nitrite levels down!
Come on people, I know its not perfect, nor far from it. I plan to keep the 3 larger Koi and maybe two of the smaller. I got to think with a biofilter running 24/7 and weekly 25% water changes should work once the ponds 'ages' ?
Doesn't a new pond take time before the nitrite break down?
fyi,
I found this on the 'net:
In figuring the stocking density of koi, this is a good rule
of thumb: One 8” Koi needs 50 gallons
One 16” Koi is equivalent to four 8” Koi and needs 200
gallons
One 24” Koi is equivalent to twelve 8” Koi and needs 600
gallons
And remember the 8” Koi this year will be 12-16” next year,
and so on! MacArthurWaterGardens: Today's Pond Q&A |
