brianp;3946189; said:If the claim is that autotrophs are not present in Stability, then I doubt that this is the case. However, I have to admit that I don't really know for sure, since the formulation is proprietary (and I asked them). The good news is that over the long-run, it really doesn't matter. I say this because eventually, the bacterial demographics of the mature biofilter will reflect the composition of the aquarium water being processed. I'm sure that the bacterial populations change over time in response to ammonia levels, feeding regimen, number of fish, etc. For example, the presence of ammonia will provide a selective growth advantage for that bacterial species which is most efficient at oxidizing it. Same with nitrite. As long as products like Stability assimilate the ammonia and nitrite initially and allow a stable biosystem to become established (pending possible substitution by other types of bacteria), they are an asset in my opinion.
Well said my friend, well said.
