Safe for aquatic life, and may be used in water used by livestock, birds, pets, and wildlife. Do not apply to water intended for human consumption.
If applying multiple packets, toss into several areas of the pond — no mixing required. For best results all season long, apply in early spring. Reapply every 4-8 weeks, or as needed, in order to maintain blue color all season long. Please note that heavy rainfall and/or intense sunlight may require additional treatment.
