Seachem Reef Zooplankton – Concentrated Nutrition for Corals & Invertebrates

Nourish Every Filter Feeder in Your Reef

Corals and invertebrates that don't get enough real marine nutrition lose color and slow their growth — and generic supplements rarely match the particle sizes your reef inhabitants actually eat.

Reef Zooplankton is a premium, concentrated blend of nutrient-rich marine zooplankton delivering essential fatty acids, proteins, vitamins, amino acids, and natural carotenoids straight to your marine ecosystem. With particle sizes from 12.5 to 500 μm, it feeds a wide variety of filter-feeding corals, marine invertebrates, and other reef inhabitants for healthy growth and vibrant coloration.

Reef Zooplankton is made by Seachem Laboratories, a science-driven chemistry company founded in 1979 in Madison, Georgia, where products are developed in-house rather than simply bottled from stock ingredients. That is why the blend targets a specific, wide particle-size range and a defined nutrient profile, and it is designed to serve as a coral-nutrition component of Seachem's coordinated reef system — feeding filter feeders and larger-particle eaters while the line's calcium, alkalinity, magnesium, and trace supplements hold the surrounding water chemistry steady. It also pairs naturally with Seachem Reef Phytoplankton to span an even broader range of feeding sizes.

1. Shake well, then add 5 mL (one capful) per 50 gallons (200 liters) of aquarium water twice weekly or as required.
2. Dose directly into your aquarium water for optimal distribution — target feeding is not recommended.
3. Refrigerate after opening (recommended but not mandatory) and always adhere to recommended dosages.
