What are the two clades of green algae?
One clade, the Chlorophyta, comprises the early diverging prasinophytes, which gave rise to the core chlorophytes. The other clade, the Streptophyta, includes the charophyte green algae from which the land plants evolved.
How did the green algae get its name?
The green lineage originated following an endosymbiotic event in which a heterotrophic eukaryotic host cell captured a cyanobacterium that became stably integrated and ultimately turned into a plastid (Archibald, 2009; Keeling, 2010).
What kind of eukaryotes are green algae?
The green lineage or Viridiplantae * includes the green algae and land plants, and is one of the major groups of oxygenic photosynthetic eukaryotes.
What kind of algae has long green threads?
In order to get answers to basic questions all around algae in the aquarium, we recommend you read this article first. Typically, filamentous algae consists of long green threads that often feel rather soft and loose. Some of them break down if you try parting a tuft.
What can I use to keep green thread algae at bay?
At first it is important to have a sufficient number of algivores in your aquarium. Invertebrates like Amano shrimp or dwarf shrimp (like Red Bee or Red Fire shrimp) will help you keep this algae type in check. Stocking up on algivores temporarily is a good solution especially if you have several tanks.
How does filamentous algae spread in the water?
In a strong current, individual filaments float in the water and get caught in decoration or plants, this is how filamentous algae spread. Quite frequently this type of algae is seen in planted aquaria that are just cycling. During the first weeks, the microbiology of recently set-up tanks is still quite unbalanced.
What do stem plants do to keep algae in check?
Especially fast-growing stem plants are really great for keeping the algae in check. The plants need to be supplied with the full range of nutrients, with liquid fertiliser and carbon (CO 2 ). In the following list you can find the target values for the individual nutritional elements:
