Medicated Food

Give the fish a day off food to build appetite

Gut fill of medicated food
It's important that all the fish get a full belly of the food. Throwing in a quarter pound of food to a pond chock full of thirty inch fish is ridiculous. The fish should eat medicated food once or twice per day until full.

Spot feeding
For best results, you could attract the fish to the side of the pond and throw them small amounts of food being careful to get the food directly to the fish which needs it.

Medicated meal 2x daily
Feed only medicated food, no other food for 10 to 14 days
Full koi are hard to kill
Eating is a good sign

Milled in versus Top dressed medicated food

Top dressed (coated) foods usually fail to work because the medications float away before the fish will eat them. The flavor is not disguised.

Medicated food with the medication milled into the food delivers the medications in your fish and not into the water
