• Do not use in steel (bare metal) tanks or troughs.
• Do not overdose stock water supplies when using this product.
• Copper should not be used in human drinking water.
• The block will add copper to the water.  Do not use in areas or districts where high copper levels are known to occur or where there is a risk of chronic copper toxicity.
• Care should be exercised with livestock fed a ration supplemented with copper or if copper bullets have been administered.
• For troughs of less than 7000-litre capacity, each 200g block should be divided into the proportion appropriate to the volume of the trough.
• If stock is suspected of having Lupinosis, remove blocks from the trough immediately.
• This product should not be used or should be used with care when the animals are already copper sufficient or have been grazing in a pasture containing plants that cause liver damage.
