Algae are primarily grown in lakes. It is a plant like organism that does not have any roots or stems, and contains chlorophyll. They can be found in both freshwater and saltwater and almost anywhere in the world. Algae grows when there is the right amount of nutrients in the like, along with phosphorus and nitrogen. Algae actually helps keep a lake productive and clean. A moderate amount of algae in a lake is common and not harmful, but when there are algae blooms, it starts to become harmful to the lake and ecosystem of the lake. These blooms can cause harm to the plants and hazard to the animals and humans in the surrounding area. Blue-green and green algae cause the most harm to a lake out of all the different types of bacteria., especially freshwater. The green algae are dangerous by forming billowing clouds of stringy or slimy algae in the water. The green algae can be hand removed but may grow back.
The Environmental Protection Agency (EPA) has approved types of algae killers called algaecides that are made out of carbonate peroxyhydrate products. They prevent the algae from blooming by invading their habitat. Another alternative to algaecides are grass carp. These are fish that are native to Asia and feed on algae. They can be farmed to be sterile, so when they are put into the lake to control the algae, the species will not over run the other fish species. Adding phosphorus to a lake will limit the growth of algae into blooming in freshwater lakes. Having high levels of phosphorus and other nutrients will cancel out the growth of algae.
