High quality barley straw wrapped up in a mesh bag to immerse in your pond. Ponstraw takes about one month to become activated by the beneficial bacteria and enzymes in your pond, then continues to prevent the growth of algae for four to six months.
Approximate size: 10" x 14", Weight: 8 oz
One bundle treats 1,000 gallons for one season.
For maximum effectiveness, Ponstraw should be placed in your pond so that there is adequate recirculation around the bundle - perfect for placing in a waterfall tank or skimmer box. If you lack the space for a bundle of Ponstraw, you may want to try Barley Pellets
or Liquid Barley Extract
