KUSURI Sinking Koi Food – Premium Low-Temperature Winter Diet
Kusuri Sinking Koi Food is a professional-grade, low-temperature diet designed specifically for Koi and all bottom-feeding pond fish. Because water temperatures drop in winter, your fish require a specialized formula that supports their slowed metabolism. Consequently, this premium winter diet delivers essential energy while protecting your koi’s digestive health during the colder months.
Why Choose Kusuri Sinking Koi Food?
- Optimized Digestion: We use high-quality White Fish Meal to ensure the 33% protein content is easily absorbed. Therefore, this reduces metabolic strain even in very cold water.
- Ideal for Bottom Feeders: This formula creates the perfect sinking diet for Sturgeon, Sterlet, Tench, and Goldfish. Additionally, it allows shy fish to feed comfortably at the pond floor.
- Immune Support: The inclusion of specific prebiotics promotes healthy gut flora. Furthermore, these ingredients boost the overall vitality of your fish during dormant periods.
- Energy Efficiency: Because these pellets sink, fish feed naturally at the bottom. As a result, they conserve vital energy by avoiding the cold upper layers of the pond.
Professional Feeding Guidelines
You should only feed your fish when the water temperature remains above 10°C. Below this threshold, the koi’s digestive system essentially shuts down. In addition, you should only provide small amounts that the fish can consume within three minutes. However, if the water temperature exceeds 15°C, you should transition back to a high-energy floating diet like Kusuri Multi-Season Food.
Technical Specifications & Ingredients
Kusuri manufactures this food using a careful cold-press process. Specifically, this ensures that the delicate vitamins and minerals stay intact. Moreover, the ingredients include essential oils that provide a rich source of Omega-3 and Omega-6 fatty acids. Ultimately, these nutrients support skin and scale health throughout the winter. In summary, transitioning to this sinking food ensures a safer winter for your entire pond population.
