The reason why I don't think it's subtilis is twofold. Firstly, all the liquid products containing subtilis are much thicker and the app rate is higher than RE. This has to do with storing inactive bacteria in a slurry emulsion w/food (either milk or molasses).
Second is the container. H&G goes through a lot of trouble to keep light and air out, and given the first reasons outlined this further leads me to believe that the bacteria are anaerobic. Plus, the reps aren't totally ignorant and 'anaerobic' isn't exactly an award winning sales term.
As for the gunk in your reservoir if the bacteria start to spread through your rez and then find the conditions unhospitable they won't be able to reproduce and will die off. It's not just living bacteria that make up bio-film (or gunk, slime, etc...) but masses of dead bacteria with living bacteria on top, eating, breeding, and shitting everywhere.
Must spread more rep... thank you Humble1~ very insightful... appreciate it!!! ;-)
