Ultrasonic algae control is a commercial technology that has been claimed to control the blooming of cyanobacteria, algae, and biofouling in lakes, and reservoirs, by using pulsed ultrasound. [ 6 ] [ 7 ] The duration of such treatment is supposed to take up to several months, depending on the water volume and algae species.
In most ponds both bacteria and algae are needed in order to maximize the decomposition of organic matter and the removal of other pollutants. [15] Algae produce oxygen (photosynthesis) and also consume oxygen (respiration), but they leave an excess of oxygen that can then be used by aerobic bacteria for respiration and for the processes of ...
Telescopium telescopium, commonly known as the telescope snail, is a species of snail in the horn snail family Potamididae found in mangrove habitats in the Indo-Pacific. [1] They are large snails that can grow up to 8 to 10 cm (3.1 to 3.9 in) in length and are easily recognizable by their cone-shaped shell.
These snails are sometimes viewed as pests in aquarium tanks with fish, because the snails create waste, reproduce very often, and are very hard to remove completely. However, some aquarium owners deliberately choose to add these freshwater pond snails to their tank because the snails will eat uneaten fish food, algae and waste, as well as ...
[3] [6] The researchers plan further fieldwork, [6] describing the ruins as "hidden in plain sight" only a 15-minute walk from Federal Highway 186 near Xpujil and cultivated farmland. [ 4 ] [ 5 ] The researchers named the site "Valeriana", after a nearby lake named Laguna la Valeriana.
The snail tolerates siltation, thrives in disturbed watersheds, and benefits from high nutrient flows allowing for filamentous green algae growth. It occurs amongst macrophytes and prefers littoral zones in lakes or slow streams with silt and organic matter substrates, but tolerates high flow environments where it can burrow into the sediment.

Costasiella kuroshimae is a selective feeder of algae from the genus Avrainvillea, [5] from which it sequesters chloroplasts into its own cells, retaining them for short-term photosynthesis. Even in the absence of active photosynthesis, chloroplasts provide a nutrient storage or "larder" that facilitates the survival of the slug without food ...
