Barley straw, from my understanding, works by inhibiting new algae growth because it emits some kind of chemical as it rots. So while you may or may not get new algae, what you will have is a rotting bale of barley straw in your pond!
You can buy barley extract - which skips the rotting part - and some people swear by it.
