Walnut Shells And Husks As Medicine/algae Killer?

[SyBenson]

Using walnut shells, leaves, extract... "which inhibit or promote recovery from aquatic bacterial, fungal, protozoan, and dinoflagellate diseases on the surface of or in the skin of the animal or from wounds and abrasions, or to control or eliminate metazoan parasites, or to control or eliminate aquatic single-celled green algae".
 
"suppressing infections and treating one or more injured or diseased aquatic vertebrate animals, by adding to the water containing the aquatic animal(s) a solution containing the extracted juice and fine particles of walnut husks or the combination of walnut husks and walnut leaves of the walnut trees of the genus Juglans, family Juglandaceae"

Came across this by accident while perusing patents.  Was wondering if anyone has heard of this, done it or have any thoughts about it?

I have never heard of using walnut shells. I have heard of coconut shells being used.
