Properly sized and operated aeration is the most $ efficient way to reduce organic sedmient over time. Mechanical removal is usually difficult to impossible (depending on pond size and the surrounding terrain) and costs more than many of us like to think about.

If the air release device (membrane diffuser, usually) is mounted on something to keep it off the bottom, out of contact with the organic debris and sediment, it shouldn't cause any cloudiness from suspension of said debris. We recently talked about such mounts in this thread, which included my DIY membrane mount.
