Such Thing As Running To Big Of A Skimmer?

[Enigma]

I think what most skimmers indicate they are rated for in gallons is for a lower bioload. My SWC 120 is rated for 120 gallons @ low bioload and 55 gallons @ high bioload.

That leads me to believe that a heavily stocked 190 should have a skimmer that is rated for 380-400 gallons.

I do believe it is possible to over-skim. I'm doing it right now, and my softies were becoming increasingly unhappy. They're now in a different tank and are very happy (with the exception of my Xenia, which may just be too far gone).
