Anyone have advice on possibly retrofitting an existing septic tank to make it an aerobic system? For example, Aero-stream sells kits where you drill a hole in your septic access lid, and run an air hose into the tank with a diffuser on the septic end and an air pump above ground. From what I understand, aerobic bacteria do a much better job of breaking down waste so that the effluent running into the drain field is much cleaner. I have a 2 chambered concrete tank, with a divider between the 2 sections that has about a 4" gap (just guessing) at the bottom. So instead of a pipe and baffle near the top of the divider to connect the 2 chambers, there is just a gap at the bottom. It looks like diffuser should be installed in the first chamber (the inlet side nearest the house). On the outlet side, there is a T baffle that extends down about 18" into the tank, and it does not have a filter. Can my tank be converted to aerobic? There is no room for me to add an additional tank to use as an aerobic chamber, I would have to work with the 2 chambered tank that I have.
