Peter from Europe writes

I have been advised that Casoron 4G Herbicide will kill blanket weed in my koi pond without harming fish. Is this true?

Answer:

No, Casaron 4G is NOT labeled to be used as an aquatic herbicide and will kill any aquatic life in your pond. Unfortunately we do not carry an algaecide to be used in small koi ponds. We recommend that you talk to a local koi pond supplier.
