Grand Champion premium koi feed combines scientific research with aquaculture expertise to give your koi optimal growth, vibrant colours and strong immunity. Here’s what makes us different from other brands:

• Unique immune-boosting blends: Specially formulated to combat gill worms and support overall koi health and robustness
• Research-backed feed formulations: Ingredients and nutrition ratios tested for torpedo-shape growth, colour enhancement and performance across varying water temperatures
• Sustainable, low CO₂ footprint: Locally sourced ingredients with environmentally responsible production close to market (Europe)

By combining science, tradition, and sustainability, Grand Champion feed delivers premium nutrition that supports healthy, vibrant koi — outperforming standard koi feeds on the market.

By prioritizing sustainability and local production in Germany, we significantly reduce our emissions and environmental impact. All our ingredients are resourced responsibly. Our low-CO₂ footprint is largely thanks to the use of by-products in our formulations. Ingredients such as fish meal and fish oil are all sourced from by-products, making our feed both nutritious and environmentally friendly.

All Grand Champion feeds are manufactured in Germany with meticulous precision and backed by rigorous quality assurance protocols. We use only premium, sustainable ingredients with fully transparent and traceable sourcing. Each formula is scientifically validated and specifically optimised for pond-based RAS systems.

Grand Champion feeds will be available from February 2026 at trusted and authorized retailers across the Netherlands, Belgium, France, Germany and the United Kingdom.

Yes. The All Season and Growth & Colour feeds are available in 2.5-mm and 5-mm pellet sizes to suit koi of various sizes.

Our advice is:

• Koi < 20cm: 2.5-mm pellet
• Koi > 20cm: 5-mm pellet

Core Balance is available in 5-mm pellets packed in 9-kg bags. All Season and Growth & Colour are available in 2.5-mm and 5-mm pellets packed in 4-kg and 9-kg bags.

Koi are cold-blooded, which means their digestion slows as water temperatures drop. Feeding should therefore be adjusted according to the season. All Season is formulated to be used throughout the entire year. It contains a balanced protein level and is easily digestible, providing energy without overloading the fish when their metabolism slows down*. Using a high-quality all-season feed helps keep koi healthy, strengthens their immune system and reduces stress.

* When the water temperature drops below 5°C, we do not recommend feeding.

To maintain optimal feed quality, we strongly recommend storing our feeds in a cool, dry place with the packaging tightly sealed. Always check the shelf life before use.

Digestibility measures how efficiently koi can absorb nutrients from their feed. Highly digestible feeds have several key benefits:

• Optimal growth and colour: Premium feeds of Grand Champion use high-quality and highly digestible ingredients to maximize nutrient absorption, resulting in torpedo-shape growth and vibrant colouration
• Better health and immunity: Easier-to-digest feeds reduce stress on koi metabolism and support a strong immune system
• Cleaner pond water: Poorly digestible feeds create waste, increasing ammonia, nitrites and cloudiness. Highly digestible feed minimises waste and maintains water quality.
• Seasonal considerations: Koi digestion slows in colder water. Using a premium feed when temperatures drop prevents gut issues and keeps koi healthy year-round.

Choosing Grand Champion means choosing feeds crafted for optimal digestibility, supporting efficient nutrient absorption and reduced waste for cleaner, clearer water.

Growth & Colour, our best koi feed, promotes torpedo-shaped growth with high-quality, easily digestible protein and enhances colour naturally with astaxanthin and spirulina.

The Grand Champion family of feeds include advanced additives like BIO-MOS®, Actigen®, Bioplex® and the Aquate™ premix. Each additive is designed to support koi health, growth and vitality.

• BIO-MOS® and Actigen® are yeast-based ingredients that support the gut and immune system, improve nutrient absorption, and strengthen the mucous barrier — your koi’s first line of defense against parasites and pathogens.
• Bioplex® provides highly bioavailable organic minerals (zinc, copper, manganese, iron) that support growth, reduce environmental impact, and improve overall performance.
• Aquate™, a proprietary premix, combines these technologies to optimize digestion, immunity and resilience across all life stages.

Together, these additives help koi maintain their vibrant colours, ideal body shape and robust health, making them especially suitable for show preparation and year-round vitality.
