Had a koi with some red streaking along its sides and a small ulcer. Microscope broke, didn’t know it. QT’d and used some iodine and debride on the ulcer, then proform-c treatment using standard protocol. Koi now been in elbagin salted to .5% for 6 days at water temp ~ 77-78 degrees.
Ammonia: zero
Nitrites: zero
Nitrates : < 5ppm
kH: 120
I’ll replace the microscope. But question, the redness went away almost immediately with the proform-c treatment and the areas that were red turned a muted brownish-grayish. Is that a sign of healing?
There are still some signs of stress, redness in fins.
