Highly concentrated water conditioner, well tolerated by animals, for the rapid and complete elimination of parasitic crustaceans that are often present in ponds, such as carp lice (Argulus), anchor worms (Lernaea), gill crustaceans, parasitic mealybugs and small crustaceans (which can act as intermediate hosts for other parasites). Product residues are biologically degraded. A water change is not necessary. Caution: Other invertebrates, such as snails, bivalves, crayfish and insects (larvae) do not tolerate this product. Plants and amphibians are not affected by the treatment.
