Scrapes done and nothing found. Water parameters are all good except phosphates. One Koi about 14 has a few sore looking areas and an ulcer. We have treated her before with ulcer swab and propolis but would like to treat her in a holding tank with Acriflavin for the 7 day period.
I can obtain a brand new IBC and have an air pump and air stones. Would this be satisfactory for her treatment?
Your help is much appreciated.
