As always, a different (and smarter) set of eyes and ears - makes a difference. Please don't think this is in any way an experiment to be published; just for kicks. Basically, in my many querries to people in the industry, the only people that have told me unequivocally that bacteria and enzymes work as claimed are the people selling it. I find that some vendors' claims that their bacteria will "digest" 24 inches of sludge in one month a little hard to swallow. I can't believe we didn't think of a control tank. We will also add a nonaerated tank with the "recommended dose" of bacteria in addition to the 2 existing nonaerated tanks that have 2x recommended dose.
As always, thanks for the great help. Control tank is now in action.
