Thanks Bill, I am getting the picture but once that compressor comes I will do a series of small tests so I know what to expect. So far I know I want the compressor in the garage..ok seems like the 1/2 black poly tubing will be fine for the run to the pond, maybe if I want I can go to 3/4. I am getting the black poly will also be ok to run into the pond, whick I will put threw the holes in a few bricks to hold it down. I need a check valve which one I dont know yet, I need a diffuser or two which one I dont know yet. I know its gonna be approx 5 foot deep and I saw a few differnt ways I would like to ancor it prob in a bucket. Like you said I can always change out the compressor and add more cfm if I need it. Here is the layout of the pond. My first thought was to put the diffuser right under where it says 6ft, I kinda would want one where it says new 8 ft but I would be happy with the one by the 6 ft mark or the 2 smaller ones, one to the left of the 6ft mark and one to the right. Trying to keep this simple what would you do?
