Mono-culture is a myth promoted by companies like Zeovit to sell their products. I'm pretty sure all of the strains of bacteria in their products (which are likely the same ones that are already in our aquariums) can be cultured with ethanol or glucose.
The thing with carbon dosing is that once your aquarium is no longer carbon limited it can build up in your aquarium. All it takes is for one thing to die off to start an oxygen depleting chain reaction as more dying corals and provide the nutrients that will be used by the bacteria until the carbon source is consumed.
