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
These have unicellular algae as endosymbionts, from diverse lineages such as the green algae, red algae, golden algae, diatoms, and dinoflagellates. [93] Mixotrophic foraminifers are particularly common in nutrient-poor oceanic waters. [95] Some forams are kleptoplastic, retaining chloroplasts from ingested algae to conduct photosynthesis. [96]
Swimming pool contaminants are introduced from environmental sources and swimmers. Affecting primarily outdoor swimming pools, environmental contaminants include windblown dirt and debris, incoming water from unsanitary sources, rain containing microscopic algae spores and droppings from birds possibly harboring disease-causing pathogens.
