🌿 Clear waters, zero algae—because your pond deserves the best!
Crystal Blue Copper Sulfate Algaecide is a 5-pound granular, aquatic-grade treatment with 99% pure Copper Sulfate Pentahydrate. Designed specifically for large ponds and water bodies, it effectively controls filamentous and string algae when water temperatures exceed 60°F. Ideal for professional and serious pond managers, it requires careful dosing to maintain aquatic oxygen levels and is not safe for sensitive fish species like Koi or Goldfish.
