Algae blossoms are caused by three aspects: excess nutrients, too much sunlight as well as reduced oxygen degrees. Nutrients come from a selection of resources, most remarkable fish as well as animal waste, fish food as well as dead/decaying vegetation. Other resources would certainly consist of plant food run-off as well as run-off from nearby farms and also fields. All of these resources give much required nitrogen as well as phosphorus that algae have to bloom as well as expand.
