BROWN MACROALGAE (PHAEOPHYTA)

Brown macro algae are abundant worldwide with most of their distribution in temperate waters as varieties of Kelp.  The brown coloration is due to the brown pigment (fucoxanthin) and individual species vary in color from yellow to dark brown, depending on the depth. There are a few tropical species of interest to hobbyists that are offered seasonally. Most however, are encountered as pests in reef aquariums and introduced on live rock. Brown algae grows prolifically under the right conditions and certain species can be difficult to remove, such as the highly invasive Dictoya.
