I have a fresh 46 gal, but I want to start a reef with fish. Way too confusing! From my research, here's what looks reasonable: hang on protein skimmer, coral/shell substrate, mh lighting with cooling fans, refractometer or glass hydrometer, live rock(Fiji the best) for a more critter diverse reef, NO UNDER GRAVEL FILTER, live coral, refugium, dual power heads. What size refugium for this tank? Will I also need a dry/bio filter? What size power heads? I prefer quality over price, but obviously please don't recommend a Mercedes when a Chrysler will do. Any help.... :strooper: :strooper:
