COPPER SULPHATE TREATMENT FOR ALGAE TROUBLES [with DISCUSSION]

George W. Fuller: I do not carry those figures very well in my mind. There has been lots of practical information obtained, and I believe it is something that is well worthy of record. Varying temperatures and varying conditions of water call for different treatment. Different kinds of organisms call for different treatment. I believe copper sulphate has a distinct field of usefulness and can be used to great advantage. It would be a good idea to get out a questionnaire and summarize the latest information.
