pond aerator [RE-wrenches]

[Windy Dankoff, Dankoff Solar]

I want to add some perspective to this topic. In my view, solar 
aeration for biological purposes (adding oxygen) is appropriate for 
very small, non-commercial applications only. The reason is that the 
most oxygen is required when the sun is NOT shining. So, economics 
may be acceptable for very small remote systems, but not larger.
