## Overview

Brightwell Aquatics PhytoGreen-M is a concentrated 10–15 micron liquid phytoplankton supplement delivering over 650 million nutrient-rich Tetraselmis cells per milliliter. Designed specifically for filter-feeding reef invertebrates, it supports coral growth, coloration, and vitality with essential omega-3s, amino acids, and chlorophyll A.

## Description

Brightwell Aquatics PhytōGreen-M is a concentrated liquid suspension of Tetraselmis, a nutrient-dense marine phytoplankton ideal for a variety of filter-feeding reef organisms. Sized between 10–15 microns, this nanoplankton is perfect for soft corals, clams, sponges, tunicates, tube worms, and larval invertebrates. 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. PhytōGreen-M does not require refrigeration but should be kept in a cool, dark place to maximize shelf life. It can be used alone or rotated with other Brightwell planktonic foods for a complete feeding regimen that matches a coral’s natural diet.
