An algaecide or algicide is a substance used for killing and preventing the growth of algae . Natural algicides Barley straw , in England , is placed in mesh bags and floated in fish pond s or water garden s 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 US and England Synthetic algicides Synthetic algicides include Copper sulphate , which is very toxic, and Polyquat .

Orphan date February 2009 Polyquat is the common name for a class of swimming pool and hot tub algaecide which is chemically mostly n alkyl dimethyl benzyl ammonium chloride some dialkyl monomethyl isomers are also included , which is also known as benzalkonium chloride . The alkyl groups are usually C14 and C16. The common name derives from the fact that these compounds are POLY alkyl QUATernary amines. R N sup sup CH3 sub 2 sub CH2 C6H5 Cl sup sup R C sub 14 sub H sub 29 sub or C sub 16 sub H sub 33 sub Pre diluted solutions of polyquat of 5 or less are sold for the hot tub market, at large mark up. It may be more economically used as the concentrated product intended for swimming pools, but in amounts scaled for hot tubs 300 gal . n alkyl dimethyl benzyl ammonium chloride is also used in some disinfecting products such as wipes including those made by companies such as Clorox .

The colour can vary from bright blue to green, because there may be a mixture of both copper carbonate and basic copper carbonate in various stages of Hydration reaction hydration . It was formerly much used as a pigment , and is still in use for artist s colours. It has also been used in some types of make up, like lipstick , although it can also be toxic to humans. It also has been used for many years as an effective algaecide in farm ponds and in aquaculture operations. Copper carbonate was the first compound to be broken down into several, separate elements copper, carbon, and oxygen . It was broken down in 1794 by the French chemist Joseph Louis Proust 1754 1826 . When burnt, it thermally decomposes to form CO sub 2 sub and Cu ... more details
