Encourages Increased Coloration through Biochrome production in Corals, Clams, & thier Allies Overview Provides numerous elements important to the formation of various biochromes (biological pigments), complex molecules that give coloration to plant and animal cells through their selective color-absorption and -reflection characteristics. Formulated specifically to provide trace quantities of elements for gradual incorporation into, and formation of, biochromes known to occur within zooxanthellae, such as chlorophylls a and c, beta carotene, and xanthophylls. Does not influence population density of zooxanthellae, which would put the overall health and survival of the host organism in a precarious situation. Formulated by a marine scientist.
