| I like to take the fish out, and put them in a large blow up pool. Mine have been over-wintered indoors this year, so not an issue. I do 5 treatments with potassium permanganate over a 9 day period. I used one teaspoon of PP for each 600 gallons of water. That should get rid of any nasties in the water!!!
I also treated the koi with praziquantel to get rid of flukes(in the holding pool). I have had a problem with them in the past. |
