Each milliliter delivers over 650 million phytoplankton cells, making this one of the most effective liquid coral foods on the market. Tetraselmis is naturally rich in omega-3 EPA, amino acids, and chlorophyll A, providing energy and essential nutrients to support coral health, reproduction, and recovery after fragging or stress. Brightwell further enhances the formula by adding a specialized amino acid shown to help intensify coral coloration. The addition of vitamin C also helps support tissue repair and overall vitality.
