Pond Boss Forums AERATION Systems questions Best pump to aerate 1/2 acre 13'

I think I'll go with $375 pump with 2 9" membrane diffusers set through 1" poly tubing (about 60'). This should keep the rig under $500.

Also I'm interested in a 230V timer. Mechanical or digital? That is the question.

Thank you all for the imput. I'll update this thread with the progress of the project. It will start in a week or two.
