If less water is to be treated, break the block proportionately. Each block contains 63gm/kg of copper, present as copper sulphate. The block should take 2-4 weeks to dissolve. Replace when nearly all dissolved. Dams and tanks should still be cleaned regularly to ensure a clean water supply._x000D_
