Prevent New Algae Growth in Ponds, Dams and Lakes
with Stephen Bros Barley Straw

Directions for Use

Clean water if possible - replace water and remove algae for best results.
Submerge net bags in water at recommended rate and allow bag to float close to water surface. Barley straw may initially release colouring into water.
Place near well oxygenated areas eg. pumps, waterfalls, inlets.
Replace straw every 4-6 months.
To maintain effectiveness, begin additional treatments one month prior to removing first bag.
Not recommended for ponds with less than 1sqm surface area.

Application Rate

Recommended rate = 50g per square meter of surface area
Calculation: barley straw required.

Further treatments may be reduced to 25g per sqm once the algae is under control.

At excessive rates of 500g per sqm de-oxygenation of water may occur

For Best Results

Add Barley straw at the start of spring before the main algae growth season.
This product will not kill algae already present ( existing algae will eventually die ), but will prevent new algae growth.
In still ponds place the Barley Straw bags in the center as this encourages even distribution of natural inhibitors.
If more than one bag is required place bags equal distances around pond.
If straw starts to smell then it is not working due to the application rate being too high. Remove and replace with new bags at correct rate.
If net bag holes are restricted by algae or silt, clear by shaking or washing in pond water.
