So just to make sure I get what your saying is that a SW environment is not conducive to all bacteria and just because you add it doesn't mean it'll grow and thrive in that environment ? How will a drastic increase in bacteria affect the anaerobic zone ? Is it possible that by adding a carbon source some pathogenic bacteria can grow exponentially and cause an imbalance and severe harm to corals ? Have you ever heard of adding probiotics to marine tanks ?
