Howdy!
My "mini-pond" is mas-o-menos about the same size as yours (the link to the project is in John's small pond thread he linked). I stocked one pound of FHM, half a pound of RR, about 25 CNBG, and 8 or so RES. .. so, not a lot. I didn't build the pond for fishing, so that is quite different than your goal, but there you can check out the pics and video of the aeration system I put in and it's been pretty great at keeping the water quality up.
Good luck with your new project!
Cheers!
Clayton
