Reef Phytoplankton – Coral & Invertebrate Nutrition (Seachem, 250 mL)

Seachem Reef Phytoplankton is a concentrated supplement designed to provide vital nutrition for corals, clams, sponges, and other filter-feeding invertebrates in reef aquariums. Formulated with a blend of phytoplankton species (2–15 microns in size), it targets the natural particle range consumed by many reef organisms. Beyond feeding, it also supplies nutrients that enhance coral coloration, growth, and overall health.

Unlike some basic coral foods, Reef Phytoplankton includes not only the plankton cells themselves but also important lipids, amino acids, and vitamins that support strong tissue development and vibrant reef life. Its liquid form makes it easy to dose directly into the aquarium or via target feeding.

⚡ In short: An essential supplement for reef tanks—promotes coral growth, boosts color, and sustains filter-feeding invertebrates with a natural plankton blend.
