Water Wurzel Barley Straw pods are made from the finest natural barley straw. They are safe to use in all outdoor ponds and water aquatic features and are a simple but very effective method of controlling algae, blanket weed and green water problems.
Water Wurzel Barley straw pods take about 2/3 weeks to become active and will work effectively for about four months. For continuous protection add a new pod approximately one month before replacing the existing pod.
Water Wurzel Barley Straw pods use dust extracted, chopped straw to give a greater surface area and to encourage a rapid growth of the micro-organisms that help keep the water clear.
Water Wurzel Barley Straw pods have an integral cork flotation aid to help keep the pod closer to the surface where oxygen saturation levels are higher. Fixing the pods near moving water (e.g. waterfalls, fountains etc.) will also aid efficiency.
Each pod in this value pack will treat approximately 4000 litres (900 gals).
