Such a difficult thing to answer but a few thoughts as :-
What's the 'tank' water volume ?
Presume you have a mature & appropriately sized filter on the tank ?
Do you test for ammonia, nitrite, pH, kH as a minimum ?
What temperature water did the koi come from ?
Salt in the water is usually used to assist with wound healing by
helping with osmosis problems or to help alleviate nitrite poisoning.
Just wondering why you have salt in the water & have you measured the
salt concentration to make sure it's not too high ?
Of course, the fish could be carrying some parisites etc and
the water quality isn't an issue? You'd need a microscope to check this.
So many possibilities and any one small thing could be an issue..... |
