Picked up 10 12" Koi from someone who bought a house with a Koi pond they didn't want.
I know the Koi won't eat the leaves but they do seem to be going after the roots as I see the plants shaking.
This weekend I'll try to drag a section of wire fence across the pond to pull up 1/4 of the Water Shield.
Depending on how well that goes might try more or go nuclear i.e. herbicide.
