Have you seen this: I think it's a dr. Tim write up.Yessir, from everything I read and from first hand experience.
Had times i needed a quick emergency setup and literally took sand out, fill up, and rockin' roll.
This of course doesn't mean that there isn't some die off, just not everything dies off.
"Nitrifying bacteria are classified as obligate chemolithotrophs. This simply means that they must use inorganic salts as an energy source and generally cannot utilize organic materials. They must oxidize ammonia and nitrites for their energy needs and fix inorganic carbon dioxide (CO2) to fulfill their carbon requirements."
"None of the Nitrobacteraceae are able to form spores. They have a complex cytomembrane (cell wall) that is surrounded by a slime matrix. All species have limited tolerance ranges and are individually sensitive to pH, dissolved oxygen levels, salt, temperature, and inhibitory chemicals. Unlike species of heterotrophic bacteria, they cannot survive any drying process without killing the organism. In water, they can survive short periods of adverse conditions by utilizing stored materials within the cell. When these materials are depleted, the bacteria die."
I wonder if that means adding bacteria on a rock or from a bottle to a new system day one, without a source of ammonia will push the bacteria to die or go dormant.....
Does that mean for adding a rock or bacterial bottle qe should add at least a fish or some soure of amonia?
