Algal blooms — phytoplankton causing the discoloration of the water. Is called rapid reproduction of algae in the pond. Can occur in fresh and marine waters, but is mainly observed in fresh stagnant waters (ponds, pools, lakes). Usually only one or a small number of phytoplankton species are involved in a particular bloom. The color of the water is given due to the high concentration of pigmented cells. Water is often green, but can also be yellow-brown or red, depending on the species of algae.
This is the result of eutrophication. Reference giant but good accepted classification of blooming types still absent. I can recommend some papers like closely near of "very good" in classifications of eutrophication:

Algal blooms may form the mat like formations on the surface of the stagnant water bodies and are responsible for negative effects on the aquatic organisms and top carnivores of the aquatic and terrestrial ecosystems. coming to the most point, among the phytoplankton mostly Blue Green algae ( Cyanobacteria) are poisonous forms which releases harmful chemical into the water bodies.Commonly known toxin producing algae are Anabaena flosaquae, A. cirninalis, Aphaniomenon sps. Aphanothece sps. Glotrichia sps. Microcystis aeruginosa, Lyngbya majasculas, Nodularia sps, Gymnodium, Gonyaulax sps. in the aquatic ecosystem. Red tide forming algal forms are species of Gymnodium and Dinophysis.
