Seachem Reef Phytoplankton 250 ml is a concentrated marine phytoplankton, designed to meet the nutritional needs of corals, filterers and tropical invertebrates. Its balanced mix of green and brown phytoplankton (size 1 to 20 μm) ensures optimal assimilation and natural stimulation of growth.
Its formula is enriched in essential fatty acids, protein, vitamins, amino acids and biological carotenoids, improving the pigmentation, vitality and natural defenses of corals. Natural carotenoids also act as powerful antioxidants.
The Reef Phytoplankton is optimized to increase the bioavailability of nutrients, allowing corals to consume less energy to assimilate proteins, lipids, pigments and vitamins.

Reef Phytoplanktontm is a mixture of marine algae mainly intended for soft corals and filterers. Reef ZooplanktonTM contains protein sources such as artemia and rotifers, ideal for LPS and SPS corals.
Refrigeration is not mandatory. The product contains preservatives that allow good stability at room temperature as long as it is stored properly.
Seachem does not offer food exclusively for copepods. However, Reef PhytoplanktonTM and Reef ZooplanktonTM can be used for feeding. Some aquariophiles use Reef Phytoplanktontm to feed rotiferous crops.
It is recommended to disperse the product directly into theaquarium instead of targeted feeding (spot-feeding). Spot-feeding can stress coral tissue. Phytoplankton should be absorbed naturally into the water column.
