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.
The impact of harmful algae blooms on the environment have a substantial effect on marine life. For example, in August 2024 the growth of the toxic algae, Pseudo-nitzschia, along California coasts were making sea lions sick and aggressive to beach goers. [44] Scientists claim this is a seasonal occurrence.
Algae are prominent in bodies of water, common in terrestrial environments, and are found in unusual environments, such as on snow and ice. Seaweeds grow mostly in shallow marine waters, under 100 m (330 ft) deep; however, some such as Navicula pennata have been recorded to a depth of 360 m (1,180 ft). [88]
In the aquarium, this algae will deteriorate if other algae is allowed to grow on its surface and should be exposed to fluorescent lighting for dense frond growth (though the algae can be grown under LED lighting). [90] 2 in (5.1 cm) [90] Green hair algae: Derbesia sp. Fast [6] Excellent [91] High [91] Yes [6]
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 ...
In this fashion, macroalgae algae growth is encouraged, competing with nuisance algae which would otherwise thrive in the main/display tank. Some also use refugiums to raise tiny brine shrimp , mysis shrimp , ostracods , amphipods , copepods and isopods for delicate fish like seahorses and dragonets to feed on. [ 2 ]
