IceCap K3-150HOB Controllable Protein Skimmer

IceCap K3-150HOB Controllable Hang-On-Back Protein Skimmer (IC-K3-150HOB)

The IceCap K3-150HOB Protein Skimmer (SKU: IC-K3-150HOB) is an authentic, high-efficiency external foam fractionator distributed by CoralVue to deliver advanced, sump-grade water purification to large sumpless marine reef aquariums and high-bioload fish displays up to 250 gallons. Standard traditional hang-on-back skimmers suffer from significant architectural limitations: they rely on hot, fixed-speed AC motors submerged directly inside the display tank, crowd your aquascape, produce distracting micro-bubble storms, and clutter your display line. The K3-150HOB completely addresses these design flaws, condensing heavy-duty organic nutrient extraction into an elegant, low-profile hang-on chassis that sits entirely outside your aquarium frame.

At the operational heart of this system is the powerful Controllable IceCap DCAIR 2.5 DC Pinwheel Pump. Utilizing the included push-button digital controller, you have precise authority over your filtration loop, allowing you to cycle the motor velocity across 10 distinct power intervals. This allows you to match the internal air-to-water ratio perfectly to your tank's unique bioload and changing surface tension. Water is drawn smoothly through a low-profile intake screen, passed immediately through the high-velocity needlewheel impeller, and diffused through a specialized baffle network. This maximizes contact time within the rectangular chamber, lifting dissolved organic waste cleanly into the collection neck before it can decay into harmful nitrates and phosphates.

Key Features

• Active 10-Speed Flow Customization: Instantly scale the pump velocity up or down at the push of a button to fine-tune your foam height or pause skimming for 10-minute coral feeding windows.

• Cabinet-Saving Low Profile Frame: Measures only 3.5 inches in depth across its main body, allowing large-scale aquariums to sit tight against living room walls.

• Subsurface Degassing Return System: Forces exiting water smoothly down below your operating waterline, trapping fine micro-bubbles internally while ensuring a splash-free, whisper-quiet loop.

• (Note: This retail package includes (1) K3-150HOB skimmer assembly, (1) high-capacity collection cup with drain line, (1) externally mounted DCAIR 2.5 pump, (1) digital controller keypad, an air silencer, and all rim-clamping hardware).
