A Natural Algae Killer for Ponds

When Barley Straw Bales are placed in water, it begins a natural decomposition process. When it decomposes it releases phenolic compounds that act similarly to hydrogen peroxide. This process is what makes Barley Straw so unique – limiting the growth of new algae over a period of time, using nothing but its natural chemical reaction in water.

How does Barley Straw work?

Barley straw works as a suppressant. When activated in water, it creates a chemical signature which affects the membrane around the algae and causes it to weaken. The algae is less likely to replicate as its cell wall could rupture which will kill it. By inhibiting its potential for growth and reproduction, the existing population is suppressed and the likelihood of any future algal blooms reduced. The best part about this product is that you can never put in too much, so you don’t have to stress about complicated measurements!

Will Barley Straw harm fish/livestock/pets/wildlife?

What do I do with used Barley Straw Bales?

Used Barley Straw Bales can be composted or turned into mulch!

Will Barley straw kill algae?

This all-natural product does not kill algae, instead it works by damaging the algal cell wall, inhibiting its potential for growth and reproduction, therefore reducing the existing population and the likelihood of any future algal blooms. Barley Straw is a preventative method and can greatly reduce the growth and reproduction of existing algae.

What is the difference between Barley Straw Bales and Barley Straw Extract?

Barley Straw Bales are in their natural state, where as Barley Straw Extract is the concentrated liquid version of the bales. When Barley Straw is activated in water, it slowly begins to decompose and releases a chemical signature that affects the cell wall of algae. Barley Straw Extract is the liquid form of the bales which is more concentrated and treats algae must faster than the bales.
