Barley Kube - 4.5 in. x 6 in. x 6 in. - 2 pk

Barley straw is a natural alternative to herbicides and chemicals for the prevention of filamentous algae in ponds. It will not harm fish or plants--in most cases it actually increases the invertebrate population providing additional food source for fish. This straw will not kill existing algae but will prevent new growth from forming.
