Tiny black spots on Ochiba

[Denise Doherty]

Firstly, good news. Flukes finally gone but not by using Fluke solv. The treatment that worked was Cloverleaf absolute fluke. Also, with some trepidation we are going to put the Koi who had dropsy back in the pond this weekend. Pine coming has gone, she is eating and now has no osmotic support from salt in her tank. It may return but we have to try and hope.
Never a dull moment with Koi and my Ochiba tiny black specks are spreading over quite a lot of her body. She isn’t quite herself and scrapes don’t reveal anything we can see. Water parameters are good although water changes are needed to keep the nitrite levels below 0.25. We did increase the Kh of the pond to 6 and now try to keep it at that by using bicarbonate of soda.
I have looked up black spot disease but there doesn’t seem to be too much information out there.
Any thoughts please?

This is the Ochiba with the black specks. I also noticed that my gold Chagoil has a couple but nothing like this. I am wondering if it is due to us needing to increase the kh from 4 to 6?
