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.
