As Fishinrod says bottom aeration usually keeps DO on the bottom and can increase decomposition of organic materials that release nutrients that could help stimulate more plant growth. Canada geese are flying toilets that produce lots of manure. OSU did a research study that showed 10 geese make the equivalent manure of 1 cow. One cow pooping in a 1/4 acre pond is a LOT of organic fertilizer. I am pretty sure that algae likes organic fertilizer.
