IceCap K3-130 In-Sump Controllable Protein Skimmer

IceCap K3-130INT Controllable In-Sump Protein Skimmer (IC-K3-130INT)

The IceCap K3-130INT Protein Skimmer (SKU: IC-K3-130INT) is an authentic, laboratory-grade internal filtration system distributed by CoralVue to bring advanced organic nutrient export to mid-sized marine reef aquariums from 80 to 140 gallons. Mechanical filters like socks or roller mats excel at catching floating detritus, but 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 K3-130INT 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 blooms.

Constructed from heavy-duty cell-cast acrylic and thick polymer components, the K3-130INT features a refined, tapering cone body engineered to calm water turbulence inside the reaction column. At its performance core is a low-voltage, Controllable 24V DC 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. This gives you precise authority over the air-to-water ratio inside the chamber. 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 real estate 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.

• Smart Anti-Overflow Safety Switch: Built-in collection cup lid sensor acts as a fail-safe, temporarily disabling the pump if the collector fills to capacity to prevent messy tank re-pollution.

• Efficient Bubble Dispersant Plate: Internally diffuses high-velocity water movement at the base of the chamber, extending air-to-water contact time while keeping micro-bubbles out of your return sump.

• (Note: This retail box includes (1) K3-130INT skimmer assembly, (1) collection cup with built-in float sensor, (1) controllable 24V DC pump, (1) digital controller, an air intake silencer, and a flexible drain tube).
