Trough Blocks 220g

Trough blocks with algaecide control algae and slime in stock troughs. One 220 gram block treats up to 7000 litres of water and lasts 2–4 weeks, requiring replacement when slime returns.

Clean the trough before use. The block adds copper to water — do not use where copper toxicity is a concern.

Active ingredients: 63g/kg copper (25g/kg copper sulphate).

For domestic stock water treatment only. Made in Australia.
