How to reduce algae in ponds?
Excess algae growth in ponds and lakes may be promoted by increased concentrations of nutrients in the water, particularly of phosphorus. These nutrients can come from a variety of sources including runoff from lawns, farms, pastures, and roads, malfunctioning septic systems, or from wildlife excrement. Several options to reduce the amount of algae in a waterbody may be available depending on the cause of the algae bloom and resources available. These include: 1 physically removing filamentous algae with rakes or nets 2 diverting nutrient-laden runoff from entering the waterbody 3 treating runoff with buffer strips of grass or other vegetation before it enters the lake or pond 4 reducing phosphorus fertilizer use and soil erosion from adjacent lawn areas 5 discouraging geese and other wildlife from frequenting the waterbody 6 avoiding disturbing pond sediments 7 using an aerator to disperse algae and minimize the effects of algal blooms and die-offs
