  2. Algal nutrient solution - Wikipedia

    en.wikipedia.org/wiki/Algal_nutrient_solution

    Algae Covered Pond. Algal nutrient solutions are made up of a mixture of chemical salts and seawater. [1] Sometimes referred to as "Growth Media", nutrient solutions (e.g., the Hoagland solution, along with carbon dioxide and light), provide the materials needed for algae to grow.

  3. Algae scrubber - Wikipedia

    en.wikipedia.org/wiki/Algae_scrubber

    Periodic removal of the algae that has grown inside of an algae scrubber removes nutrients (ammonia, nitrate, phosphate) from the aquarium water, thus providing the needed filtration. An algae scrubber is a water filtering device which uses light to grow algae; in this process, undesirable chemicals are removed from the water. [1]

  4. Freshwater aquarium algae - Wikipedia

    en.wikipedia.org/wiki/Freshwater_aquarium_algae

    Species may be unintentionally disseminated through spores and fragments that hitchhike on ornamental fish and plants purchased from aquarium suppliers. [1] Algae is typically considered a nuisance and subject to removal through the use of algicides and the release of algae eaters. However, total elimination of algae is considered unlikely in a ...

    Algae can be used to capture fertilizers in runoff from farms. When subsequently harvested, the enriched algae can be used as fertilizer. Aquaria and ponds can be filtered using algae, which absorb nutrients from the water in a device called an algae scrubber, also known as an algae turf scrubber. [129] [130]

  6. Algaculture - Wikipedia

    en.wikipedia.org/wiki/Algaculture

    Dulse is one of many edible algae. Algaculture may become an important part of a healthy and sustainable food system [11]. Several species of algae are raised for food. While algae have qualities of a sustainable food source, "producing highly digestible proteins, lipids, and carbohydrates, and are rich in essential fatty acids, vitamins, and minerals" and e.g. having a high protein ...

  7. Eutrophication - Wikipedia

    en.wikipedia.org/wiki/Eutrophication

    One response to added amounts of nutrients in aquatic ecosystems is the rapid growth of microscopic algae, creating an algal bloom. In freshwater ecosystems , the formation of floating algal blooms are commonly nitrogen-fixing cyanobacteria (blue-green algae).

  8. Marine food web - Wikipedia

    en.wikipedia.org/wiki/Marine_food_web

    The pelagic food web, showing the central involvement of marine microorganisms in how the ocean imports nutrients from and then exports them back to the atmosphere and ocean floor. A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton.

  9. Marine protists - Wikipedia

    en.wikipedia.org/wiki/Marine_protists

    Marine algae can be divided into six groups: green, red and brown algae, euglenophytes, dinoflagellates and diatoms. Dinoflagellates and diatoms are important components of marine algae and have their own sections below. Euglenophytes are a phylum of unicellular flagellates with only a few marine members. Not all algae are microscopic.
