Hey Zach if your a do it yourself kind of guy check out this link below. It's very simular to my orignal RC51 setup and mine has been working great now for almost 4 years in my 1 acre pond. I run mine 12 hours a day from dusk till dawn.
I have modified mine as of late though and am running it with 2 diffusers instead of 3. Only because my 1 fuser was gunked up pretty bad and I could not get it cleaned up so I just plugged it off. It runs good either way I think I actually have a little more upwelling of water with just 2 fusers as I don't have to push air to a 3rd fuser.
If your pond is over 10 feet deep though I would look for something a little stronger as far as a pump goes. I have mine is 8 to 9 feet and it does just fine. Of course if your wanting someone to give you a turn key operation then there are some great folks on this site that can surely help you with that as well.
