Algaecide
From Wikipedia, the free encyclopedia
An algaecide or algicide is a substance used for killing and preventing the growth of algae.
[edit] Natural algicides
Barley straw, in England, is placed in mesh bags and floated in fish ponds or water gardens to help reduce algal growth without harming pond plants and animals. Barley straw has not been approved by the United States Environmental Protection Agency (EPA) for use as a pesticide and its effectiveness as an algaecide in ponds has produced mixed results during university testing in the United States and England
[edit] Synthetic algicides
Synthetic algicides include Copper sulphate, which is very toxic, and Polyquat.
