Feeding Guidelines
Feeding amounts vary depending on water temperature, season, and koi activity level.
✓
Start with a measured cup or bowl for consistency.
✓
Feed that amount over approximately 10 minutes.
✓
Observe behavior and appetite before adjusting.
During peak summer feeding, koi may consume multiple measured portions per day. As temperatures cool in fall, gradually reduce feeding amounts to align with activity levels.
Two to three feedings per day are typical during active seasons. Legacy Sinking Koi Food has been tested for safe feeding in water temperatures down to 36°F*, allowing flexibility across seasonal transitions.
How to use Primary Diet Sinking in your feeding plan
- Use as your primary, year‑round diet for shy or bottom‑oriented koi
- Combine with floating pellets if you have a mix of bold and timid fish
- Transition gradually (over 7–10 days) when switching from another brand to allow koi and filtration to adjust.

Primary Diet Sinking: Full-Spectrum Nutrition Below the Surface
Not every koi feeds at the surface. Shy fish, bottom-oriented fish, and koi in ponds with heavy surface competition often miss out when floating pellets are the only option. Primary Diet Sinking solves that without compromising on what’s in the formula.
The nutritional foundation is identical to the Legacy Floating diet — herring meal as the primary protein source, algae-derived DHA, beta carotene for hi color development, and FOS prebiotics for gut flora balance and efficient digestion. The difference is format, not quality.
Pellets sink gradually, allowing koi to feed at the depth where they’re most comfortable. Less surface disruption, less competition, and less food swept into skimmers before it can be eaten.
Formulated for feeding down to 36°F, Primary Diet Sinking works as a true year-round diet without requiring a seasonal formula switch.

What’s Actually in the Sinking Koi Food Formula
Primary Diet Sinking is built around animal-based protein — herring meal specifically — because it delivers the complete amino acid profile that supports body conformation and muscle development in a way plant-based fillers can’t replicate. No corn, no cheap cereal binding agents.
Potato starch provides digestible energy without the waste load that grain-heavy formulas produce. Combined with FOS prebiotics that support gut flora balance, the result is higher nutrient absorption per pellet and significantly less waste output — which directly affects your water quality and filter load.
The micronutrient profile covers the full vitamin and mineral stack, including algae-derived DHA for neurological health and coat condition, and beta carotene targeting the hi color pigmentation pathway at the source.
Made in the USA. Every bag is manufactured domestically with strict quality control and no artificial colors, flavor enhancers, or ingredient shortcuts.
Ash content is kept low by design. Less filler means less waste, cleaner water, and fewer water changes.
Q: Can I feed Primary Diet Sinking year round?
A: Yes. Primary Diet Sinking is proven suitable for year round feeding when used according to water temperature and koi activity.
Q: Is this food made in the USA?
A: Yes. Kenzen koi food is manufactured in the USA, with strict quality control and a focus on clean, purposeful ingredients.
Q: Will this food cloud my water?
A: The highly digestible formula and absence of cheap fillers reduce waste, which helps support clearer water and healthier filters when fed correctly.
