The 1532 would easily mix your pond. I have a Gast diaphragm compressor, .9 cfm at 10 psi. I run 300 feet of 1/2" poly connected to a weighted garden soaker hose. My pond is a little larger than yours and my Rainbows did well through a hot dry summer. I ran it 24/7 until the heat of summer and then only when air temps were cooler than the water temp, usually at night or cool cloudy days. Since I have trout, I have to be careful with warming the water and my system easily de-stratified my small pond. The $40 price tag is too good to pass up. 3/4" black poly water line is cheap as is the soaker hose. Should work excellent for you. Btw, the soaker hose idea was from Bob Koerber, some time ago. This may not apply to you, but it didn't create enough surface boil to keep an area ice free this winter. No suprise for me. John
