So, not to beat a dead horse but are you guys saying you wouldn't run aeration (in shallow / 10% of the pond) ALL of the time but simply turn it on when the pond has had snow on it for a week or two blocking sunlight? And even then, only run it until it pops a hole through and then shut it down until it happens again?
I normally run 3 diffusers in the summer and running one now but I had too much pressure from running just a single diffuser so I stuck a hose into the edge and let it bleed off the pressure (stuck it under a pile of pallets to keep it there). That "bubbler" alone opens 10-15 feet diameter and I don't think it "circulates" near the water that the diffuser does - maybe just run that open line without the diffuser?
