ATB Econo Skimmer 840 & ATB Econo Skimmer 1050

Half the price and half the neck size. It seems worth it to get the larger skimmer (ATB). The new Super Reef XP-2000 cone will blow both of these skimmers away for the price and performance. The skimmer has the same base and neck dimensions as the ATB and uses the new Bubble Blaster pump that will draw 1,400 LPH of air for $400! That's much cheaper than the I-Tech 400 and ATB 840. It's cheaper than the I-Tech 200 which is much smaller than the XP-2000.
