So I'm thinking of having a custom 400 gallon built by glass cages and the one question I have is which overflow style I should go with? It will be a mixed reef with predator type fish in it. I'm tossing between the center style overflow and a herbie style or something I have never used before which is there coast to coast type over flow all along the back. Which is better or are they the same? Which would be quiter as well ? Thanks
