There are many algaecidal products marketed towards usage in aquariums and ponds.
I have been annoyed by the distinct overall lack of easily accessible information regarding these products and what they contain, and information on the nature of and safety precautions one should take around the ingredients.
To save others the hours I have spent hunting down information, I have decided to make my notes into this public information thread.
The goal is, with the community's help, to compile a comprehensive list of Algaecides and their ingredients, preferably including concentration where this is available.
I have chosen to sort the Algaecides by their primary active ingredient.
The purpose of this thread is not to debate whether or not one should use algaecides, any discussion on this must go in a separate thread!
