Description WSD Trough Blox – Trough Block Algaecide WSD Trough Blox are slow-release copper blocks designed to control algae and slime in livestock water troughs. Each 200 g block provides effective algae control and also supplies a copper supplement to stock. Suitable for use in plastic and concrete troughs, they are safe for milking sheep, dairy cattle, and dairy goats. What are WSD Trough Blox? These blocks contain copper sulfate (63 g/kg) and dissolve slowly in trough water, reducing harmful biofilm and toxic algal growth. They keep water clean and fresh while supporting animal health with added copper supplementation. Why Choose WSD Trough Blox? Algae and slime control: Keeps stock water clean and clear for up to 8 weeks. Dual benefit: Provides supplementary copper for livestock. Safe for milk producers: Approved for use with dairy cattle, goats, and milking sheep. Nil withholding period: No meat or milk withholding requirements. Convenient: Easy to place in troughs with minimal maintenance required. How to Use Place one block per 7000 L of trough capacity (divide block proportionally for smaller troughs). Blocks last 4–8 weeks; replace when slime begins to return. Do not use in steel or bare metal troughs. Do not overdose water supplies; copper should not be used in human drinking water. Take care in areas with high copper levels or where livestock diets are already supplemented with copper.
