thanks burgemeister,

It looks like I have 660 foot run to the pond and it is a half acre tear dropped shape 12 foot at the deepest. I want to run the 3/4 or 1 inch air supply to the pond. Just looking breifly it looks like a max 15 psi, 1.5 cfm 1/4 horse pump would be ok? It is a down hill run to the pond, I am wondering if that would make a difference?
I went to the gast site, where do you find pricing for these pumps?


A little snow, Please!
