Bill and guys thanks for all the feedback , I will do some more reading on Wood's experiences. I am still thinking that due to the depth of my pond, I may run 1 aerator in the shallow end , and even turn on the aerator in the deep end once and a while through the winter.

I am still concerned about the airlines as they enter the pond, currently my lines enter the shallow end of the pond on the ground as the compressor is located on the edge of the pond. Will the black poly line handle the pressure of the ice forming around it without busting ?

I think I have a work around the moisture problem in the lines . I am going to install a desiccant air dryer that uses the pellets to absorb moisture installed after the compressor inline before the air enters the poly pipe going under the ice. These things are cheap and also easy to make.

Any thoughts on this ? Thanks again for all the help.
