Will copper sulphate affect pond plants and frogs in a pond with algae?

Hi Paul,

We would not recommend that you apply copper sulphate to a pond where frogs are present. We clearly say on the label that this product is dangerous to fish and the same would apply to frogs. There is a natural product that can be applied in ponds that will stop the algae and is also pet friendly. I am sure you will find more information online.
