While the exact mechanism of action remains unclear, researchers think bio-active compounds are produced as the straw decomposes in the presence of oxygen and sunlight. These bio-active agents apparently favor the development of desirable water plants over undesirable microscopic and filamentous algae. Two major drawbacks to the use of raw barley straw, whether, loose, in bales or in pellet form, are:1. Adding these materials to the pond is aesthetically unappealing.2. It is necessary to wait for the material to decompose, sometimes several days, before any effect is noticeable.The benefits of certain types of bacteria to aquatic ecosystems, whether natural or manmade, is well-documented. Bacteria are essential to the recycling of toxic fish wastes. They also produce vitamins and other factors needed by pond plants and fish. Establishing an equilibrium population of beneficial bacteria in a garden pond depends upon several factors and should not be left to chance.Aqualife Barley Extract is superior to other barley straw products because:1. It eliminates the need for unsightly, bulky material that takes a long time to break down.2. It contains billions of living, beneficial bacteria to quickly establish a healthy microbial equilibrium in the pond.
