Any body of water without chemical conditioning becomes, over time, a living environment, supporting the life of two kingdoms: the Plant kingdom (algae and other aquatic plants) and the Animal kingdom (bacteria, protozoa, insects, fish, etc.).
Environmental conditions
It also happens that environmental conditions influence and affect the balance of this ecosystem (fertilizer run off, for example), to favor the development of one kingdom over the other.
Very often, in aquatic environments shaped by humans, it is the Plant kingdom that is favored, with the explosion of algae, cyanobacteria and invasive aquatic plants. This imbalance will favor in time eutrophication of the water body.
Control methods
Two methods have been developed for the control of algae and cyanobacteria.
