Pond Plants Direct - A White Water Lily
Barley Straw For Green Water
Our Barley Straw Bales are 100% natural and the eco-friendly solution to pond algae problems.

The decomposition of the correct volume of our barley straw creates humic substances that will inhibit the growth of algae.

When placed in water each bale will float on the surface where the majority of algal growth takes place and the oxygen levels are higher, thereby increasing the effectiveness of the straw.

Calculate the volume of your pond by multiplying (in feet) the length by the width by the depth then multiply the total by 6.25 to give you the volume in gallons, or use our handy volume calculator located below.

Each pack contains 4 bales and 1 bale will treat up to 1000 gallons (4500 ltrs)

Barley bales are most effective when placed in running water, for example near a waterfall, pump or filter box outlet. Our barley bales can even be placed directly into the pond filter box.

At temperatures below 10°c allow 6 to 8 weeks for bales to become effective, and 3 to 4 weeks at temperatures above 10°c Bales should be replaced every 6 months. Always add new bales one month before removal of the exhausted ones to maintain continuity.
