Use Crystal Blue® Copper Sulfate Smart Crystals to treat algae mates in your pond or intrusive root systems in your septic tank. As with any other pesticide or algaecide, follow manufacturer's directions for application rates and procedures. The active ingredient in the smart crystals is copper sulfate pentahydrate. 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.
