I took Paul’s advice with the Terramycin powder mixed into Koi food.

I used 250g Koi food, 2g Terramycin, 4g Vitamins and 2 teaspoons fresh garlic.
Mixed the Terramycin, Vita and garlic in a glass of water and added it to the plastic container containing the food. Waited about 15minutes for food to get soft, then added clay to form putty.










How I am going to have a beer and I hope this info will be useful to someone ( not the beer part)
