what does algaecide do
Which algaecide will work best for your particular situation depends on the type of algae growth you are experiencing in your pool. For example, most algaecides are effective against green algae, but black algae may require an algaecide specifically formulated to treat this resistant type.hile the chlorine you use for regular pool maintenance and water sanitization does have bactericidal and algaecidal properties, the addition of pool algaecide will enhance and prolong the effectiveness of the chlorine and can act as a valuable backup to the anti-algae effects of regular chlorination.
