Laguna Barley Straw helps maintain superior pond
water conditions in a completely natural way. The barley straw comes in small
slow-release pellet form for easy handling and convenience. Simply place the
pellets in a mesh bag (included) and immerse in the water. Over the next several
weeks, the pellets will release an enzyme that helps promote clean and healthy
pond water. The barley straw is completely natural and will not harm fish or
plant life. One 2.5 lb (1.13 kg) bag treats 1250 US gallons (4730 L) and lasts
12 weeks. Includes a reusable mesh bag with closure.
