The All-Around Professional Formula

Not every koi keeper is chasing maximum growth or prepping fish for a show. Most of us just want healthy, vibrant, long-lived fish that look great in the pond year-round. That’s exactly what Blackwater Gold-N Professional was designed to deliver — a premium, well-rounded formula that covers all the nutritional bases without the specialization of a growth or color-specific food.

Gold-N Professional is the formula we recommend most often to hobbyists who want a single high-quality food they can feed with confidence across a wide range of fish, pond sizes, and seasons.

What Sets Gold-N Professional Apart

The formula includes:

• High-quality fish meal and shrimp meal for a complete amino acid profile
• Stabilized vitamin C to support immune function
• Natural color enhancers (spirulina and carotenoids) to maintain baseline color
• Probiotics to support digestive health and improve nutrient absorption

Who It’s For

• Hobbyists who want a single premium staple food
• Ponds with a mix of fish at different life stages
• Keepers transitioning away from big-box store foods
• Goldfish keepers — equally well-suited for koi and goldfish

Feeding Recommendations

Feed 2–3 times daily during active feeding season (water temps above 55°F), offering only what your fish consume in 3–5 minutes. As water temperatures drop below 60°F, transition to Blackwater Cool Season formula.
