Update on two two sick koi put in QT last weekend:
-- when pulled from main pond, I treated both with Tricide Neo, paste/qtip method for 5 mins under anesthesia, put into QT (QT has 300 gallons, 3 mag drive pumps w filters running, had some ammonia (.50), now down to zero, using Prime, salt around .15, 25% water change/48 hrs)
-- Also treated the Bekko 2 x a day, for 2 days (total of 4 additional treatments) of pull/spray with TN/put back in QT after 3-5 mins. Did this a few days ago, so the pictures you see are from yesterday. A little improvement in the middle of the big sore. He acts normally
-- Also installed a heater 3 days ago in QT and got the temperature up to 75 degrees (was 60 degrees last weekend)
-- The blueish-colored fish immediately stabilized last weekend, after TN, sores looked to be healing over, then in last two days sores have turned red again.
Also did Proform C/Prazi 3-day treatment in 7,400 gal pond with main population of koi.
Any suggestions as to what I should do next to speed their recovery in QT? Medicine directly into the water? Pull and re-treat with TN?
