I also was going to say EXCELLENT CHOICE going with an SWC Skimmer. I have a 250a ,pre-cone design but it rocks. I don't have any experience with thier cone designs, but I know they're always willing to answer questions by phone and have pretty good customer service. One of if not the best choice i've made in equitment purchasing since I started reefing. SWC w/Askoll pumps all the way. Just my 38cents.
