Kiyomizu Koi Food
Life-Stage Nutrition for Long-Term Health, Shape & Water Quality
 
Kiyomizu Koi Food is a scientifically structured nutrition range built around one core principle: koi require different nutrients at different stages of life. Rather than overloading fish with ingredients that may be counterproductive, Kiyomizu delivers three precisely balanced formulas—Junior, Adult, and Jumbo—each designed to support healthy development, longevity, and stable water quality.
This approach mirrors best practice in animal nutrition and reflects modern advances in koi husbandry, water quality management, and pond design.
 
Why Life-Stage Feeding Matters
As koi grow, their metabolism, growth rate, body development, and nutritional tolerance change:
Young koi require growth-supporting, highly digestible nutrition
Adult koi need body shape refinement, colour support, and health stability
Jumbo koi benefit from less protein—but of higher quality—to protect organs and maximise lifespan
 
Feeding according to life stage:
Improves long-term health and vitality
Prevents nutrient overload
Optimises water quality by reducing organic waste
Shared Kiyomizu Core Formula (All Stages)
All Kiyomizu diets are built from scratch using premium ingredients and the latest nutritional science:
BIO-MOS (mannan oligosaccharides)
Prebiotics & probiotics for gut health
Easily digestible, high-quality proteins
Astaxanthin for controlled colour development
Organically bonded vitamins & trace minerals
Special algae products (Omega-3 support)
Montmorillonite clay (bentonite) for digestion & water quality
Yeast extracts & digestion-enhancing ingredients
This formulation improves nutrient absorption and helps maintain cleaner pond water.
 
KIYOMIZU JUNIOR – 4.5 mm
For Koi up to 35 cm
Junior koi need a strong foundation to develop into future jumbo koi.
Designed to support:
Healthy growth and bone development
Strong immune response
High digestibility for young digestive systems
Balanced proteins, vitamins, and minerals ensure rapid but controlled development without stressing fish or filtration.
 
KIYOMIZU ADULT – 6 mm
For Koi 35–60 cm
As koi mature, growth slows and body shape and colour refinement become priorities.
Key benefits:
Prebiotics & probiotics to strengthen long-term health
Controlled protein levels to prevent excessive growth stress
Ingredients that support colour development and vitality
Clean digestion for improved water quality
Analytical Components (Adult)
Crude protein: 40%
Crude fat: 8%
Crude fibre: 3.2%
Crude ash: 7.6%
Adult feeding is where many ponds fail—Kiyomizu Adult prevents over-nutrition while maintaining condition.
 
KIYOMIZU JUMBO – 8 mm
For Koi 60 cm+
Jumbo koi do not benefit from high protein diets. Excess protein can reduce lifespan and damage organ health.
Jumbo formula focuses on:
Smaller amounts of very high-quality, easily digestible protein
Maximum support for health, colour, and longevity
Helping koi reach their genetic size potential naturally
This is nutrition designed for koi that may live decades—not seasons.
 
Feeding Guidance (All Kiyomizu Diets)
Feed 1–3 times daily
Only feed what koi consume within 5 minutes
Remove uneaten food
Below 10 °C: reduce feeding
Below 5 °C: do not feed
 
If keeping koi of mixed sizes:
Start with largest pellets first
Introduce smaller pellets once larger koi are feeding
 
Bottom Line
Kiyomizu Koi Food represents a new standard in koi nutrition—built on biology, not marketing. By feeding koi according to their life stage, you protect health, refine body shape, enhance colour naturally, and maintain better water quality over the long term.
For koi keepers focused on longevity, condition, and professional-level results, Kiyomizu is a disciplined, intelligent feeding system—not just another bag of food.
