fucoxanthin

Brown Algae. Phaeophyceae or brown algae are distinguished by chloroplasts that have four surrounding membranes, thylakoids in stacks of three, fucoxanthin that masks chlorophyll-a and -c, laminarin as the photosynthetic reserve, and alginates commonly as the wall matrix component.

Brown algae are used to produced alginates, which are employed as food additives and in industrial manufacturing. Their common uses include as food thickeners and fillers as well as stabilizers for the ionization process of batteries.

The body (thallus) of Phaeophyceae lack vascular tissues as seen in tracheophytes. Thus, brown algae do not have true roots, stems, and leaves. The root-like structure of the brown algae is referred to as the holdfast.

Brown algae, (class Phaeophyceae), class of about 1,500 species of algae in the division Chromophyta, common in cold waters along continental coasts.

There are about 1800 species of brown algae, and most are marine. In general, brown algae are larger and more species are found in colder waters.

Batrachospermum is a freshwater red alga widely distributed in tropical, sub-tropical and temperate areas. Gelidium amansii is an economically important species of red algae commonly found in shallow cost of many East and Southeast Asian-countries.

Laminaria is a genus of brown seaweed in the order Laminariales (kelp), comprising 31 species native to the north Atlantic and northern Pacific Oceans. Some species are called Devil’s apron, due to their shape, or sea colander, due to the perforations present on the lamina.

They both need light to grow, they eat organic wastes like nitrates (NO3-) and phosphates (PO4) out of the water column. And they can both be a real pain in the butt if they get out of control in your tank. What makes brown algae different from true algae is that it also needs silica (SiO2) to live, but algae does not.

API MARINE ALGAEFIX Algae Control effectively controls these types of algae: Green algae, “Red Slime”, and “Brown algae” in saltwater aquariums. Works fast. Will not harm marine fish, corals or other invertebrates when used as directed.

What Are The Best Algae-Eating Fish?

• Bristlenose Plecostomus (Bristlenose plecos) Bristlenose plecos are a great addition to most aquariums.
• Siamese Algae Eater.
• Chinese Algae Eater.
• Otocinclus Catfish.
• Twig Catfish.
• Nerite Snail.
• Cherry Shrimp.
• Amano Shrimp.

To use a razor blade to scrape away algae, hold the blade at a 45-degree angle to the tank wall and gently scrape at the algae. If you keep up with your weekly water changes, you should not have a problem with excess algae growth in your freshwater tank.

Algae is beneficial to an aquatic ecosystem; however, when levels get too high there can be problems. Some algae can release toxic compounds, but the most common source of fish kills related to algae is oxygen depletion. It is the extraction of oxygen for respiration in water at night that causes most fish kills.

“Green Water” outbreaks are caused by a sudden population explosion of suspended algae known as phytoplankton. Unlike other algae species that grow on the glass or objects in the aquarium, green water algae float about the tank and multiply by the billions in a short period of time, in what’s known as a “bloom”.
