I am in the early stages of setting up a 75 gallon reef tank. I know I need a skimmer but the more I read about them the more confused I get. Do the downdraft models perform better? Are venturi models better than airstones? I am thinking about getting an Aqua C EV-120 or an Aqua Medic Turbofloater T1000 for placement in a sump. Can anyone give a recommendation for the skimmer, sump and pump? Also I am interested in joining a club in the NYC area (Queens, Manhatten, Brooklyn) if anyone knows of any. Thanks
