Tall vs Wiiiiide skimmers

[Pescador]

I have two Euroreefs (CS8-3 and CS6-3) both are the same height but one is the 8 inch width and one is the 6 inch. They are the same pumps on both. The six inch outperforms the bigger one in amounts of skimmate. But like Albert says I think it depends alot on the pump and the bigger one might be underpowered. They now sell CS8-3 with a two pump option that recircs and probably is longer dwell time which might be a better way to go. But they are great skimmers, no adjusting after its set, just clean the air venturi regularly if you have a calcium reactor or are dosing kalk.
