This is the very best DOC remover for a sump less saltwater aquariums up to 125 gallons. Powered by our super efficient Bubble Blaster HY-1000 Pump. Cone skimmers have been a huge hit for the last few years now. The benefit of the XP cone design is that it puts very little back pressure on the pump because there is little resistance from the base of the skimmer all the way up to the collection cup. Less resistance means more skimming ability for the pump to work at its maximum output. We now have brought the cone design into a HOB skimmer.
