The answer on my aerator pipe, is YES, it is working perfectly. The scum layer is undisturbed, and the color of the exit water is a perfect light gray, indicating no sludge being circulated. Additionally the effluent filter is clean (not clogged up with sludge). See "Breakthrough on my aeration problem" near the end of my report,
I'll post a message here when my testing of this breakthrough is complete in the next few weeks.
Which side of the tank are planning to put your aerator? Input side out output side? I suggest the input side to digest the max amount of sludge, then the output side will trap whatever is left over, or whatever is stirred up to escape into the output side. I suggest waiting for my breakthrough report.
