Pond Champs Blue Lake and Pond Dye 1-Gallon adds a natural blue color to ponds — the blue tint blocks sunlight penetration, which limits algae growth. Pond dye serves a dual purpose: it makes the pond look better AND suppresses algae by reducing the light algae needs to grow. 1 gallon treats a large pond area. Safe for fish, wildlife, and irrigation. Available in Galion, OH.
