IceCap K3-200 In-Sump Controllable Protein Skimmer

IceCap K3-200INT Controllable In-Sump Protein Skimmer (IC-K3-200INT)

The IceCap K3-200INT Protein Skimmer (SKU: IC-K3-200INT) is an authentic, laboratory-grade internal filtration system distributed by CoralVue to bring advanced, controllable organic nutrient export to large marine reef aquariums and high-bioload fish displays up to 300 gallons. While mechanical filters like filter socks or roller mats excel at catching floating detritus, dissolved proteins from organic wastes and uneaten foods remain trapped in the liquid column. Left to decay, these compounds break down directly into harmful nitrates and phosphates. The K3-200INT serves as your frontline defense, utilizing high-velocity air integration to physically bind, float, and remove these dissolved organics from your aquarium system entirely before they can trigger unwanted algae outbreaks or stress delicate stony corals.

Constructed from heavy-duty cell-cast acrylic and thick polymer components, the K3-200INT features a large 8-inch reaction column optimized to maximize contact time within a highly space-efficient frame. At its performance core is the efficient, low-voltage Controllable DCAIR 4.0 Pinwheel Pump. Unlike old-school AC pumps that run at a single loud speed, this DC driver allows you to throttle the motor velocity across 10 distinct power intervals via an external digital controller, giving you absolute authority over the air-to-water ratio inside the chamber. This high-performance motor pulls an impressive 1,200 liters per hour of air while consuming a maximum of 35 watts of power. Combined with a pipeless gear output valve that discharges water smoothly underneath the baseline to eliminate splashes, this skimmer delivers dead-silent operation while protecting your cabinet from humidity and salt spray.

Key Features

• Active 10-Speed Flow Customization: Adjust pump power settings at the click of a button to quickly fine-tune your bubble height or stall the system for coral feeding windows.

• Cabinet-Saving Space Configuration: Maximizes your filtration area by housing the large water pump entirely within the lower base framework of the skimmer cavity.

• Quiet Submerged Discharge: Internal gate configuration routes effluent water cleanly out of the lower base below the operating waterline, stopping trickling noises.

• (Note: This retail box includes (1) K3-200INT skimmer assembly, (1) collection cup with lid, (1) controllable DCAIR 4.0 pump, (1) digital 10-speed controller, an air intake silencer, and a flexible collection cup drain tube).
