Microbe-Lift Fish Food Guide

The Microbe-Lift® Koi & Fish Food line offers a tailored feeding solution for each season, stage of growth, and type of fish in your pond. From cold-water formulas to high-protein summer blends and immune-boosting options, each product is designed to support fish health, color, digestion, and vitality.

Choose the right food based on water temperature, fish size, and your management goals, whether that’s preparing for winter, promoting growth, or maintaining vibrant coloration.

Seasonal Feeding Guide

Matching your fish food to the season is one of the simplest ways to promote vibrant, healthy fish and a clean pond environment. Microbe‑Lift’s seasonal formulas are tailored to the physiological needs of koi and goldfish throughout the year—offering support for digestion, immunity, and growth exactly when it's needed most.

Spring & Fall — Transition Periods

During transitional months like early spring and late fall, your fish are recovering from or preparing for colder temperatures. Their metabolism slows significantly, and digestion becomes more difficult—especially under 55°F (13°C). That’s why Cold Weather Food is formulated with easily digestible wheat germ and stabilized Vitamin C to reduce stress on internal organs. It provides just the right balance of protein and fats without overburdening the digestive system.

In early spring, fish are often more vulnerable to pathogens and water quality fluctuations. This is where Immuno Food plays a crucial role—its enhanced vitamin profile and montmorillonite clay content help rebuild immune function after winter dormancy or stressful maintenance events. These formulas together ensure your fish transition safely into active months or back into cooler periods.

Summer (Warm Months) — Peak Growth

Summer brings warm water, increased activity, and peak feeding demand. Fish grow fastest during this time, and their nutritional needs rise accordingly. Summer Staple Food offers a reliable, everyday floating formula to sustain their energy and boost coloration without overwhelming the water with excess waste. For more aggressive growth goals—especially in show koi or young fish—Growth & Energy adds a high-protein punch to support muscle development and weight gain.

To round out the seasonal diet, Fruits & Greens delivers fiber, vitamins, and natural plant content to support digestion and maintain a healthy gut biome. For mature koi, Big Bites offers a large pellet format with dense nutrition that’s easier for big mouths to consume and digest efficiently. This well-balanced summer rotation ensures your fish stay energized, colorful, and healthy during the most active months of the year.

All Year / Anytime — Versatility & Support

Some fish foods are formulated to work in any season, and Microbe‑Lift’s all‑year options do just that. Variety Mix combines staple, growth, and plant-based pellets into one convenient blend—perfect for those who want to simplify feeding while still giving fish access to a balanced, diverse diet. It’s also a great choice for households with different types or sizes of fish in the same pond.

For smaller or juvenile fish, Mini Pellets ensure every fish can safely feed, while avoiding overfeeding and waste. These pellets are also well-suited for automatic feeders. Meanwhile, Sinking Pellets serve bottom-dwelling or timid fish who prefer not to compete at the surface. These formulas provide dependable nutrition any time of year and are excellent supplements to your seasonal rotation.


Fish Size & Pellet Format

Feeding properly according to fish size is just as important as seasonal timing. Small juvenile koi and goldfish benefit most from micro-sized floating pellets like Mini Pellets, which are easy to consume and reduce waste. For bottom-dwelling or timid fish that don’t compete at the surface, Sinking Pellets ensure they get the nutrition they need. Mature koi over 10″ thrive on Big Bites, a larger floating pellet designed for their appetite and jaw size. Many of Microbe‑Lift’s floating diets, such as Variety Mix, Cold Weather Food, and Summer Staple Food, are suitable for fish of all sizes when fed in appropriate amounts.

Always align feeding routines with water temperature—warmer water means faster digestion, while cold water slows metabolism and requires gentler formulas. If your fish show signs of stress or are recovering from illness, Immuno Food offers immune support during vulnerable periods. Rotating between complete formulas like Variety Mix and seasonal supplements like Fruits & Greens ensures balanced nutrition throughout the year.
