It’s best used as a preventative treatment—place it in your pond early in spring before algae blooms form, and leave it in place all season.

For best results, replace when the straw turns black and maintain a regular stock to ensure continuous algae prevention. While barley straw helps inhibit algae growth, combining it with good pond care practices—such as shading with aquatic plants, reducing excess nutrients, and preventing leaf litter—will create the healthiest, clearest pond environment.
