Recreational ponds, wastewater lagoons, fish grow-out ponds and small, shallow lakes have always exhibited the problem of organic matter collecting on the bottom and eventually becoming polluted. Wastewater lagoons are especially fraught with problems because their purpose is to clean the wastewater to the point that it can be released back into the environment. Over the years many different things have been attempted to assist in degrading the organic matter that builds up in the “sludge” on the bottom of these water bodies.
