IceCap K1-50 Protein Skimmer

IceCap K1-50 Compact In-Sump Protein Skimmer (IC-K1-50)

The IceCap K1-50 Protein Skimmer (SKU: IC-K1-50) is an authentic, master-crafted marine filtration assembly distributed by CoralVue to deliver commercial-grade protein skimming into highly confined under-cabinet sump filtration arrays. Mechanical filtration like filter socks or rollers can only catch solid organic particles, leaving dissolved proteins from fish waste and uneaten foods to accumulate and break down into harmful nitrate and phosphate over time. The K1-50 serves as your primary water purification system, utilizing an intensive air-induction mechanism to physically bind, trap, and extract these dissolved organic compounds out of your marine ecosystem entirely before they can trigger invasive nuisance algae outbreaks or stress delicate stony corals.

Constructed entirely from heavy-wall cell-cast acrylic and robust marine-grade PVC, the K1-50 stands up to years of continuous high-salinity exposure. At its operational core is the highly efficient IceCap DCAIR-700 DC Pinwheel Pump. This low-voltage driver draws air through a specialized silencer and shatters it against an optimized needlewheel impeller, packing the compact 3-inch reaction chamber with a dense cloud of micro-bubbles while sipping just 6 watts of power. To combat the footprint issues common with standard external-pump skimmers, IceCap integrates the pump cleanly inside the reaction chamber. Backed by a pipeless horizontal gate valve design, this skimmer provides splash-free discharge below your operating water line, keeping under-cabinet hardware dry and silent.

Key Features

• Maximizes Organic Waste Extraction: Pulls dark, concentrated organic waste out of the water column, instantly lowering biological oxygen demand and raising aquarium redox levels.

• Ultra-Sensitive Pipeless Tuning: Horizontal control dial offers incremental gate height adjustments, allowing you to seamlessly dial in a dry or wet foam level.

• Reef-Safe Structural Materials: Built with entirely non-conductive, corrosion-proof components to ensure zero chemical leaching inside sensitive marine reef environments.

• (Note: This retail box includes (1) K1-50 skimmer body, (1) collection cup with lid, (1) integrated DCAIR-700 DC pump, an inline air silencer, an optional hanging bracket, and a flexible collection cup drain tube).
