One month ago, I installed my home-made aeration system. Basically , for a 1/3 acre pond, I simply used an old 1/4 horse compressor and ran clear tubing with splitters and (3) 12 inch air diffusers. My pond was so muddy, I was down right ashamed! Today, the water is clear at least a foot down, maybe more and the BG seem to bite better than ever! I guess they can see the bait finally! If anyone doubts that adding air will help, do it! I believe you will be more than satisfied!
