This chemical dissolves in water to free up the free copper that inhibits photo synthesis in the algae. Copper sulfate smart crystals can be added to algae mats in granular for or dissolved water solution. Apply directly to the algae mats. Wait a minimum of 14 days between applications. For best results, use in the spring when algae starts to grow.
