I see most people on here talk about air pumps when it comes to aeration. From what I can find on the web, yours is a small fan in shallow water. When i google pond aeration, i see water fountains too.
Why did you choose the fan over an air compressor or fountain?
Which of the three causes the least evaporation?
Which of the three cools the water the least in winter, and heats it the least is summer?
