Best Answer

The brown seaweeds are tough and able to live in wave-exposed waters near the surface. They are the most common seaweeds of the intertidal rocky shore, usually found in and below the sublitoral fringe.

If you are talking about brown Algae in an aquarium, they thrive in an environment with a high amount of light, whether sunlight or artificial, and they "eat" phosphates, which are released from a huge variety of sources, carbon filters, fish waste and leftover food, etcetera.

If you are wanting to get rid of it, the best way is to use an algae eater, such as a Plecostomus or Otoclincis catfish. (Contrary to popular belief, snails are NOT good algae eaters, as they only snack on the top layer, and will only do that if no other food is available). Another option is to perform daily partial-water changes and scrub all of the algae so it does not take hold on the walls and decorations of the aquarium. The daily water changes will remove the phosphates and make survival difficult. More live plants is also effective, as it causes the algae to fight for nutrients.

(From Wikipedia, the free encyclopedia)

The Phaeophyceae or brown algae, (singular: alga) is a large group of mostly marine multicellular algae, including many seaweeds of colder Northern Hemisphere waters. They play an important role in marine environments both as food, and for the habitats they form. For instance Macrocystis, a member of the Laminariales or kelps, may reach 60 m in length, and forms prominent underwater forests. Another example is Sargassum, which creates unique habitats in the tropical waters of the Sargasso Sea.

Many brown algae such as members of the order Fucales are commonly found along rocky seashores. Some members of the class are used as food for humans.

Worldwide there are about 1500-2000 species of brown algae.[4] Some species are of sufficient commercial importance, such as Ascophyllum nodosum, that they have become subjects of extensive research in their own right.[5]

Brown algae belong to a very large group, the Heterokontophyta, a eukaryotic group of organisms distinguished most prominently by having chloroplasts surrounded by four membranes, suggesting an origin from a symbiotic relationship between a basal eukaryote and another eukaryotic organism. Most brown algae contain the pigment fucoxanthin, which is responsible for the distinctive greenish-brown color that gives them their name. Brown algae are unique among heterokonts in developing into multicellular forms with differentiated tissues, but they reproduce by means of flagellate spores and gametes, which closely resemble other heterokont cells. Genetic studies show their closest relatives to be the yellow-green algae.

Brown algae is found mostly in the cold waters of the Northern Hemisphere. The largest and fastest growing seaweeds are classified as brown algae.
