Pond Boss Forums AQUATIC VEGETATION Balance of plants in the environment The most oxygen producing aquatic plants??

Plants with the highest rate of photosynthesis are your top Oxygen producers. Unfortunately, with this high rate comes a high growth rate causing the plant to be classified as either a 'Nuisance' plant or outright Invasive.
Elodea is one such plant and, if I remember correctly, is classified as invasive in some states.
