Koi live in mudponds in Japan. There is NO salt there. They stay in mud ponds for 7 months out of 12. Then as many one and two year olds as possible are sold off.
The better breeders introduce fresh water all day long during the 5 months indoors. There would be no way to keep salt levels up?
Only when it gets too expensive to heat the water is the flow of well water cut back.
Kodama is a dealer with a facility in Chiba, that is part of Tokyo. The breeders of Japan are in the Mountains of Niigata, Hiroshima and scattered in the West and the South.
I'm sure some breeder/dealers use a lot of salt- but that would be in the months of Nov and Dec soon after the late October/early Nov. harvests.
