Versatile, 99% pure copper sulfate pentahydrate for agricultural, pond, and livestock management. Fully water-soluble with zero fillers or binders, our lab-tested crystals deliver a predictable, consistent copper concentration for precise dosing every time.

Multi-Purpose Applications

  • Pond & Pool Management: Highly effective for targeted algae control.

  • Orchard & Garden Care: Easily dissolves to prepare custom Bordeaux mixture for plant disease management programs.

  • Soil Amendment: Corrects confirmed copper deficiencies in sandy and high-organic soils (supports enzyme systems, photosynthesis, and cell wall formation).

  • Livestock Care: Ideal for mixing into routine cattle, sheep, and horse hoof footbaths.

Purity & Quality Standards

  • 99% Pure ($\text{CuSO}_4\cdot5\text{H}_2\text{O}$): Stable crystalline form keeps its potency indefinitely when stored in a cool, dry place.

  • Lab Verified: CDFA registered and third-party lab tested for heavy metals, with results consistently well below required safety limits.

⚠️ Important Application & Safety Guidelines

  • Never use metal: Always dissolve crystals in a plastic, fiberglass, or wooden container.

  • Test before applying: Potency is high; always test water alkalinity or run a soil test prior to dosing. Follow exact rates appropriate to your specific site.

  • Storage & Disposal: Keep away from children, pets, food, feed, and drinking water. Check local municipal regulations before any drain-line use.
