Understanding the micro-biome. This is the pursuit of understanding how carbon and bacteria dosing fit into this network. Network? Yes, a network or symphony of diversity, working symbiotically, each understanding purpose and role. Whether you have a vast system, with different bio-omes or biotopes are created, or whether you run super clean, no rock, no bio media, and rely on the holobient bacteria to drive the overall biome, giving little competition, all approaches at some point want to find a balance. Another words, with tons of space, we could mimic this with DSB, remote DSB, fuge zone, cryptic zone, with copious amounts of life, micro life, etc, therefore aiding in this advanced micro-biome. Or, perhaps we choose to take a more stripped down approach, running with less diversity, but less competition, allowing this holobient bacteria out compete nuisances. Adding a Probiotic type bacteria addition method, in this environment would be advantageous. That said, I tend to believe that all systems, regardless, are being stripped, with mechanical filtration, hindering this natural driving balance. Best systems I have ever run with acropora have no socks hindering the natural foods ever present in our systems.
