Anyone wanting healthy and productive livestock of any kind will appreciate the importance of providing an adequate supply of clean water. Trough Blox are for use in any concrete or plastic water trough to prevent algal growth.
Each block contains 63gm/kg of copper, present as copper sulphate.
Use one block in 7,000 litres (1,500 gal) of water.
Break up block for smaller troughs. The block should last 2-4 weeks.
Replace when block is nearly all dissolved.
Note: Troughs should still be cleaned regularly to ensure clean water is provided to stock
