From my knowledge, aerators can have some impact on the phosphorus compounds that are being recycled from decay of bottom sediments, especialy in presence of anaerobic conditons. BUT I have never seen research or proof that aerators can decrease or suppress the dissolved nutrients (nitrogen or phosphorus) that already occurs in water flowing or rinsing into a pond or lake. Under these conditions aeration (bubbling or spraying) has little impact to stiffle the algae growing affects of nutrients. I think this explains why some see algae decreases with aeration whereas others see little impact from an aerator. Anyone know of research that shows otherwise?..
