Controlling Algae in Golf Course Ponds

Every year many seem to forget about algae control in their ponds until mid-summer when algae mats and blooms start consuming ponds. A recent article in Aquatics Magazine, Volume 33/ Number 2, Fall 2011 addresses this problem. In the article, "The Importance of Nutrient Management in Ponds," Cullen Danner, a Lakes Technician with Aquatic Eco-Systems, Inc., talks about the role of nutrients in algae growth.

Article Highlights

    • Weed and algae control are often the most substantial part of managing a pond.
    • Nutrients (carbon, nitrogen & phosphorus) are ever present in pond systems and are the food source for plants and algae.
    • Nutrients naturally occur in ponds from the first day they are filled with water.
    • Internal contributors to phosphorus in your ponds include fish and waterfowl waste, decomposing vegetation and decaying aquatic organisms, such as algae.
    • External sources of phosphorus include leaf litter, grass clippings, fertilizer runoff, and even well water and rain.
    • Alum (aluminum sulfate) has a strong chemical affinity for phosphorus.
    • Algal cells can no longer use nutrients when they are bound to alum.
