Salt Treatment - Day 2 - Evening

I checked the salinity of the pond. It dropped to 0.08%. I'm guessing there is some diluting of the pond. Even though, I backwashed the filters and lowered the pond level about 4 inches and I diverted the stream that feeds the pond, the pond refilled. There must be some spill over from the bogs into the pond.

The pond also is spilling into the bogs and waterfalls to the lower pond. I tested the water in the lower pond and it's at 0.03%.

I made a mistake on the temperature, or it seems to be warming up.
Temp: 46 degrees F
Salt: 0.08%

I added another 80 pounds of salt. I'll test the water again in the morning.

I lost a small 3" fish. He was dead in the filter, without a tail. I don't know if it was the fin rot or a raccoon. Also the Ogon Koi in the first two pictures seems to be listing to the side. I hope I don't loose her.

Of the 60 Koi I have, only about 2 seem to be very sick, and another 4 have traces of illness.

For reference, below is a mosaic of some of my Koi:
