No thread...I just try to be helpful to others and pass the info along whenever it is relevant. I wouldn't have bothered with it until Seachem informed me that these were bacterial "spores", upon which the entire picture shifted. In my hands, it performed flawlessly. I can not imagine a more effortless cycling method. One caveat, however, whenever I cycle a new tank (by whatever method), I always add some cane sugar initially as a carbon source.
BTW, I agree there that there is considerable "plasticity" within the bacterial population colonizing the biomedia. I would think that not only does the bacterial count fluctuate, but the "demographics" as well, in response to the bioload confronting it.
