I don't know if you nano dudes would know this. But what do you think of the Berlin method of filtration? Here is the methodology I have with my 125. Deep sand bed with live sand mixed in with aragonite substrate(3 inches minimum), Lots of Live rock(at least 50% of the tank full of it), and an aqua c remora pro hang on skimmer with mag 3. If my single aqua c doesn't do the job I may buy another one. So what do you fellas think of that? Do I really need all of those gizmos and gadgets these bigger tanks all seem to have? I was already in over my head buying a 125 in the first place. I really don't want to buy all of that extra junk such as a sump, calcium reactor, etc. Your input would be appreciated.
