Product Description


Kusuri Premium Koi Food

Premium Koi Food is a very high quality Koi food which was scientifically developed at Exeter University in the late 1990’s. Three years research undertaken by PhD students discovered that the addition of Kusuri Klay improved digestibility by up to 22%. This is the reason coupled with the other high quality ingredients that Kusuri’s Premium, Multiseason and Wheatgerm have incredibly low levels of fish waste. Promoting optimum health and growth.



Kusuri Premium Koi Food is the most popular food in the Kusuri range. A very high quality, immune enhancing, food for Koi.

We have formulated our food to provide the correct balance of ingredients for Koi. Kusuri Products are the only manufacturer to include Kusuri Klay in their researched food.

Exeter University Biology Department, 18 years ago, discovered that the addition of Kusuri Klay removed stress proteins from the digestive tract. Stress proteins come from feeding food that contains airborne spores of Fungi and Algae. This subsequently inhibits the fish’s ability to absorb and digest food efficiently, this can lead to poor growth and health.

Kusuri Klay has the effect of cleansing the digestive tract, allowing the high quality ingredients to be absorbed, keeping your fish happy and healthy.


Key benefits include:

  • Garlic to reduce parasitic infestations.
  • Kusuri Klay for better digestion of up to 22%.
