Other products put all kinds of bacteria in one bottle. Why not ATM?
It is unrealistic for a product to contain bacteria for bio-filtration of ammonia and nitrite (aerobic autotrophs) and bacteria for organic consumption in the same bottle and form a viable product. Many products make this claim, but in doing so reject the some of the most fundamental biological principles of the microbes in question.
Bacteria that consume organics like in Outbreak! are heterotroph bacteria, which are spore-forming. Bacteria that consume NH3 and NO2 like in Colony are non spore-forming bacteria and cannot be packaged with spore-forming bacteria. The reason is that in order to keep spore-forming bacteria in their spores for long-term storage, special inhibitors are used. These inhibitors would kill non spore-forming bacteria on contact. This is why both kinds of bacteria cannot be kept viable in the same bottle over time.
This is just the facts of it.
