Description: My 125 gallon tank has dual overflow chambers, and uses a Megaflow model 4 for wet/dry filtration. I also have a Fluval 304 for the polishing. I then have 4 korolia powerheads turned on/off randomly from a Red Sea Wavemaster Pro. The tank also contains 150 lbs of lace rock and 200 pounds of crushed coral.
Advice: Know as much about the creatures you plan on keeping before you ever actually have them.
