Amiracle Wet/dry, Emperor 400 with carbon media and nitrate sponge, Magnum 350 with micron filter, Red Sea Turbo Berlin skimmer, 1" live sand, four pounds of live rock.
The only problem that I have with my 125g tanks is that the nitrates get up pretty high every couple of weeks or so. However my tanks are full of sloppy sharks and invertebrates. Nitrates being higher than normal isn't a rare thing for me. This setup seems to work exceptionally well.
I also have a 150 gallon with the same things as above only 3" of live sand, 50 pounds of live rock, and a Rainbow Lifeguard fluidized bed filter.
