This would tell you the most cost effective material but it wouldn't tell you the most effective bacteria. To determine the most effective bacteria you would have to determine what the organism concentration or count is. Probiotics list this information on their product label but pond bacteria does not. Contacting the manufacturer may be an option if determining the best bacteria is your goal but then again any of the information that you obtain from your samples will only be applicable to your particular water sample and it's conditions (pH etc.)

I wouldn't stir the samples at all. If someone is going to aerate then they won't need to add bacteria.
