THE FORMULA. THE REASONING.
THE RESULT.

Kenzen was formulated for serious keepers. The ingredient label shows you why.

The Legacy Line uses herring meal as the primary protein source — a marine protein that delivers the complete amino acid profile needed for body conformation, muscle development, and consistent growth. Algae-derived DHA, beta carotene for hi color development, and FOS prebiotics support absorption at the gut level, meaning less waste output and cleaner pond water as a direct result.

It feeds effectively down to 36°F. One formula, year-round.

The Kenzen Legacy Line includes a floating primary diet, a sinking primary diet, and Chasers treats. Kenzen Koi Food starts at $75 per bag and ships directly to keepers across the US.

Incredible Growth and Color of Koi

I cannot believe the difference in growth and deeper color in my 20 year+ koi after deciding to ‘gamble’ on Kenzen Koi Food Primary Diet Floating 7mm pellets. In the 2 years I have been using this amazing product, my fish have grown more than they did in the last 10 years. Neighbors, family, and friends have also noticed and commented on their remarkable growth, the brilliant sheen, and deeper coloration of each fish.

Great Koi Food for Growth

Great product for growth. It must taste good too. My fish enjoy the sinking pellets. I was turned on to Kenzen by a koi breeder and I have been feeding my fish for almost 10 years with this great diet.
