The IceCap K3-100HOB Protein Skimmer (SKU: IC-K3-100HOB) is an authentic, high-efficiency external foam fractionator distributed by CoralVue to deliver professional-grade water purification to sump-less marine aquariums from 40 to 100 gallons. Traditional hang-on-back skimmers often suffer from common design flaws: they utilize noisy, hot AC pumps submerged inside the display tank, take up valuable real estate, spit millions of micro-bubbles into the water column, and overflow onto living room floors when clogged. The K3-100HOB addresses every single one of these complaints, condensing advanced, sump-grade skimming dynamics into a sleek, narrow-profile external hang-on chassis.
At the core of this system is its innovative Controllable 24V DC Skimmer Pump. Utilizing an external digital keypad, you can fine-tune the pump's operational speed across 10 distinct power intervals. This allows you to match the internal air-and-water ratio perfectly to your tank's unique bio-load profile. Rather than using standard underwater pipe intakes that draw clean water from mid-depths, the K3-100HOB features a surface-skimming overflow box. This box skims off the organic surface slick—where the highest concentration of dissolved proteins collects—and routes it directly down past the needlewheel impeller. The resulting slurry undergoes multi-stage diffusion before rising into the collection neck, extracting waste before it can break down into harmful nitrates.
Active 10-Speed Flow Calibration: Lets you increase or decrease pump intensity at the push of a button to quickly fine-tune your foam line or pause skimming for feeding routines.
Advanced Dual-Chamber Silhouette: Features a dedicated, isolated bubble reduction track that traps air micro-bubbles, returning crystal-clear, degassed water to your display.
Ultra-Narrow Cabinet Separation Profile: Requires less than 4 inches of physical clearance behind your tank rim, sliding easily into tight under-cabinet or against-wall gaps
