Soluble carbohydrates released from the surface of the straw act on the monocellular green water algae causing them to clump together (flocculate) and sink to the bottom of the pond. In this way green water is often cleared in just a few days. Making the best use of the oxygen in water, safe aerobic decomposition is assured and the natural compounds which keep ponds clear are released into the water. The process continues for about six months giving long term protection.
