I can understand the logic behind the starter strands of bacteria. Rationally, the Biodigest has one billion or so bacterial cells. It is kept in a tiny 1-3ml vial. Even if this was extremely concentrated, I find it hard to believe that the live sand does not have at least teh same quantity of bacteria, say one billion cells in 3-4 square inches.
Therefore this seems logical that the biodigest is a starter colony. Without a proper fuel source growth is limited. This leads me to believe that the contributing factor to overdosing is the fuel source.
Bacteria multiply in hours. If plenty of food source is available in the aquaria at the time of dosing Biodigest, then it seems reasonable that an overwhelming population of bacteria may exist in 24 hours. Thus, RTN disease may be a result of a bacterial infection of corals due to an overwhelming bloom of the bacteria, because of overdosing a fuel.
On the flip side, one may argue that if you only dose 1/2 a billion cells then the first generation offspring will double to 1 billion cells, which is where we would have started if a whole vial was dosed.
I'm not sure where the OD faults lay, but these are some ideas to toos around. Any thoughts?
