Q: My pond is about a quarter acre, and I have ducks so I don’t want to use chemicals. Can I use barley straw?

A: More and more people are using barley straw as an all-natural (and duck friendly) way to control pond scum—and for good reason. Barley straw is a safe, natural alternative to manufactured chemicals and one of the compounds produced by submerged, decomposing barley straw may actually help keep your pond clear.
You need a lot of it to be effective.
In your quarter-acre pond, you’d need between 25 and 50 pounds (1 to 2 standard bales) of barley straw, depending on your pond’s condition. That straw would then need to be broken up, divided among several permeable bags and placed around the perimeter of the pond with weights in water no deeper than 6 feet.
That’s a lot of work!
And if you don’t replace the barley straw as it decomposes, it just turns into more decaying organic debris in the pond.
So what are your options?
You can give barley straw a try or you may want to reconsider manufactured chemicals, like Algae Defense®. The algaecide has no water use restrictions, and it’s safe to use around ducks and other wildlife. And because it only needs to be used when algae growth is occurs, you could use it as a one-time algae bomb. Not all chemicals are bad!
