Four of my koi are showing signs of some type of flesh eating disease.
Two have a hole in their side (Doitsu); two have it on the lips (standard scaled koi). The smallest of the group died (both lips were eaten away)
The 3 living patients were removed from the pond and put into a 135 gallon hospital tank, then into smaller 20 and 25 gallon tanks.
I have been treating them daily with Oxolium for 3+- weeks. One shows some improvement (smallest koi – 8”), one looks the same (medium – 10”), but the largest – 12” had actually gotten worse.
I performed 50%-60% water changes every 3 days+- on the quarantine tanks (then added new medicine and salt)
During treatment I raised the salt level to 4ppt +-
I have an 800-900 gallon pond made of stainless steel. Filters are a Laguna Bio falls 5000 fed by a Laguna Max Flo 2400 pump (on bottom of pond). I also have a Laguna Pressure Flo 2100 uvc fed by a Pondmaster Supreme 1200 via a skimmer box. Both feed a waterfall.
I realize that I over filter the water, but was hoping over filtration would help avoid any problems like I'm experiencing now.
All water parameters (that I check) appear perfect. Ammonia and Nitrate are 0; Nitrates less than 40 ppm (frequent water changes with declorinators); PH is always near 7.6. The water is crystal clear. Temp is in the low 70’s (72-74 degrees F).
Any ideas how to get rid of this illness?
Can anyone recommend any other medications to try?
Thanks, Paul
