I never intended this post to be a pump vs air compressor thing. I am using the pump in this fashion strictly because I already own the pump and I wanted to derive a way to use it so that it gives me the best results for what I have. Besides, I really don't like the noise or the unnatural look of the boiling effect that air gives. I was just more or less curious about why I couldn't find more people using pumps in this way over other applications. I'm not all that surprised that compressors are more efficient, and I'm sure that it is even more so for larger bodies of water. It does seem to me that they do have their limitations in their usage, especially in smaller ponds. I guess I will just keep people posted as to how it works out for me.
