Reef-building stony corals (hermatypic corals) require endosymbiotic algae from the genus Symbiodinium to be in a healthy condition. [69] The loss of Symbiodinium from the host is known as coral bleaching, a condition which leads to the deterioration of a reef.

Porphyra is a genus of coldwater seaweeds that grow in cold, shallow seawater. More specifically, it belongs to red algae phylum of laver species (from which comes laverbread), comprising approximately 70 species. [2] It grows in the intertidal zone, typically between the upper intertidal zone and the splash zone in cold waters of temperate oceans.
Chlorella is a genus of about thirteen species of single-celled or colonial green algae of the division Chlorophyta.The cells are spherical in shape, about 2 to 10 μm in diameter, and are without flagella.
Spirogyra (common names include water silk, mermaid's tresses, and blanket weed) is a genus of filamentous charophyte green algae of the order Zygnematales, named for the helical or spiral arrangement of the chloroplasts that is characteristic of the genus. Spirogyra species, of which there are more than 500, are commonly found in freshwater ...
Cupricide is a chelated copper product that eliminates blooms with lower toxicity risks than copper sulfate. Dosage recommendations vary from 190 mL to 4.8 L per 1000 m 2. [274] Ferric alum treatments at the rate of 50 mg/L will reduce algae blooms.
Pink algae is a growth of pink, slimey bacterial matter which can sometimes occur in pools and laboratory equipment. The name is a misnomer, because pink algae is not a true algae but is actually caused by a bacterium in the genus Methylobacterium. The color of the bacterial growth comes from pigments within its cells.
Most edible seaweeds are marine algae whereas most freshwater algae are toxic. Some marine algae contain acids that irritate the digestion canal, while others can have a laxative and electrolyte-balancing effect. [7] Most marine macroalgae are nontoxic in normal quantities, but members of the genus Lyngbya are potentially lethal. [8]
