That was my initial response after reading your experience. But after installing aerators to the leach lines and turning structure and having the ability to monitor it all, I figured I didn't have much to lose. Anyway another confirmatory data point for your side. I still wish the filter had worked. Are you familiar with this style, and do you think it could have performed better? http://www.septicsolutions.com/SepticTankFilters/EffluentFilters.html#925
