HOW OFTEN:Once algae growth is under control, add one dose every 5 days. Weekly doses of Algaecide will control growth and reduce pond/fountain maintenance.

HOW TO: Before using Algaecide, make certain that the pond has vigorous aeration. Thoroughly mix Algaecide into pond/fountain by adding near the pump outflow, waterfall, or aeration device. Algaecide can be mixed in a bucket of pond/ fountain water; repeat dose every three days until algae is controlled. Be prepared to siphon out dead filamentous algae.
