I was having leakage from one of my tanks I have a 3 tanks system no fields. We used the bubblier of the aero stream in our 2nd tank . The smell of the septic tank that gets pumped is so unnoticeable when you open the cover now so I know it is working. The leakage of the last tank the top of the tank was broken and so we fixed that The ground water that we use to get there has gone down immensely and no smell now . So far so good and its been 6 months now .
