However, there may be thousands of species of algae with this growth form, and an identification is rarely certain. [10] Green thread algae is common in newly established aquaria and is easily outcompeted by installed plants. [9] Hair algae is very similar to green thread algae. Typically, hair algae grows in a carpet of dense, short filaments.
Algae (UK: / ˈ æ l ɡ iː / AL-ghee, US: / ˈ æ l dʒ iː / AL-jee; [3] sg.: alga / ˈ æ l ɡ ə / AL-gə) is an informal term for any organisms of a large and diverse group of photosynthetic eukaryotes, which include species from multiple distinct clades.
Algal bloom commonly refers to the rapid growth of microscopic unicellular algae, not macroscopic algae. An example of a macroscopic algal bloom is a kelp forest . Algal blooms are the result of a nutrient, like nitrogen or phosphorus from various sources (for example fertilizer runoff or other forms of nutrient pollution ), entering the ...
Brown algae (sg.: alga) are a large group of multicellular algae comprising the class Phaeophyceae. They include many seaweeds located in colder waters of the Northern Hemisphere. Brown algae are the major seaweeds of the temperate and polar regions. Many brown algae, such as members of the order Fucales, commonly grow
Also known as Spaghetti algae and Green hair algae (not Derbesia). This hardy algae is composed of clumped, long filaments, thicker and more brittle than those of Chaetomorpha linum. It is an excellent addition for refugiums, serving as habitat for microinvertebrates and providing nutrient export. [72] [71] 20 in (50.8 cm) [74] Green tide alga
Audouinella, also known as black algae, [1] is a widespread genus of red algae, found in marine and freshwater environments. [ 2 ] The form known as " black brush algae " (or " black beard algae ", BBA for short) is a particular nuisance in aquaria , since most algae eater fish and invertebrates avoid it.
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 ...
Cladophora is a genus of reticulated filamentous green algae in the class Ulvophyceae. They may be referred to as reticulated algae , branching algae , [ 1 ] or blanket weed . [ 2 ] The genus has a worldwide distribution and is harvested for use as a food and medicine.
