Mostly marine, with unicellular or multicellular body. Cells are eukaryotic, with special type of excretory granules in vesicles. Chief pigments are chlorophyll a and c, beta carotene, lutein, fucoxanthin, dioxanthin and violaxanthin. Reserve food includes laminarin, mannitol and oils.
What is the most common brown algae?
kelps
The rockweeds and leathery kelps are often the most conspicuous algae in their habitats. Kelps can range in size from the 60-centimeter-tall (2 ft) sea palm Postelsia to the giant kelp Macrocystis pyrifera, which grows to over 50 m (150 ft) long and is the largest of all the algae.
What is the function of the holdfast in brown algae?

Does Clorox kill algae in a pool?
Added Clorox to Green Pool. Muriatic Acid lowers pH and Total Alkalinity (TA). It does not kill algae. You can swim within an hour of adding most concentrated chemicals into the pool — possibly even after 15 minutes or so if your circulation is very good.
Can algae in a Pool Hurt You?
Algae, although unsightly, will not hurt you. However, bacteria feeding on algae waste becomes a problem. Bacteria multiple in the heated environment of a swimming pool, and swallowing, breathing or coming in contact with these germs can lead to many illnesses.
