RC51's system was for shallower water. I looked at doing it for a 12-14' deep pond and decided I wouldnt get enough out of the air pump he was using. Now if you upgrade that, no reason that I can see that you can't buy it in pieces and put it together yourself...

Give a few country boys a little money, beer, an arc welder and power tools and great things can happen...or someone is going to the hospital or jail.
