l graze on the string algae in the pond. Only feed the fish what they can consume within a few minutes. Fish food that is not eaten by fish will decompose in the pond and increase nutrient levels. Fix Leaks
: Tap water can have an abundance of nutrients in it. Continually adding large quantities of tap water to compensate for a leak can actually promote algae growth. Fix leaks when they are discovered. Control Run-Off:
Never use lawn fertilizer or insecticides on trees around your pond or on areas of your property that will drain toward your pond. Lawn fertilizer and insecticides will cause large algae blooms, as well as severely threaten the aquatic life inside your pond. Remove Debris:
Keep your pond free of debris. Don’t let the skimmer debris net overfill with leaves. Decaying debris in the skimmer will contribute to unwanted nutrients.
