Aluminum Sulfate, or alum, has long been used as a water clarifying agent and rapid phosphorus binder. Depending on weather conditions, several applications throughout the season may be required. Alum has the potential to rapidly drop water pH. This rapid change has the potential to negatively impact aquatic life. Monitoring pH during applications is highly recommended.
